CROSS REFERENCE TO RELATED ORDERS
[001] This application claims the priority benefit of Provisional Patent Application n2U.S. 62 / 271,963, filed on December 28, 2015, the disclosure of which is incorporated in this application as a reference in its entirety. TECHNICAL FIELD
[002] The present technology is generally aimed at dynamic supply in coke ovens for heat recovery in relation to the operation and output of coke plants. BACKGROUND
[003] Coke is a solid carbon fuel and carbon source used to melt and reduce iron ore in steel production. In a process, known as the “Thompson Coking Process”, coke is produced by pulverized coal by batch feeding into an oven that is sealed and heated to very high temperatures for approximately forty-eight hours under closely controlled atmospheric conditions . Coking ovens have been used for many years to convert coal into metallurgical coke. During the coking process, finely ground coal is heated under controlled temperature conditions to devolatize the coal and form a coke melt that has a predetermined porosity and strength.
[004] Coal particles or a mixture of coal particles are supplied, or loaded, in the hot furnaces and the coal is heated in the furnaces. Due to the high temperature of the furnaces during the filling process, the coal feeding process needs to use conveyors to transport coal particles horizontally in the furnaces and provide an elongated bed of coal. The conveyor, which is manually controlled by an operator, enters the ovens from an opening on the pusher side and supplies coal in the oven as it extends towards an opening on the coke side at the opposite end of the oven. Once the conveyor reaches the opposite end and finishes filling the bed, the conveyor retracts from the oven from the same side as it entered. Once filled, the oven is sealed and heated to form coke.
[005] The manual filling of an oven in this way commonly results in a non-uniform coal bed profile. More specifically, opposite ends of the coal bed will normally have a different thickness of material, with the coal near the opening on the pusher side having a significantly greater thickness than the coal near the opening on the coke side. As a result of the non-uniform bed profile, the coal portion on the slender side is coked much faster and experiences a greater burning loss. Supplying the furnace in this way also commonly leads to inconsistent coke quality and short furnace supply, in which a coal capacity less than the full potential of the furnace is loaded. The overall effect is coke quality, output and coke yield for a reduced coke production facility. BRIEF DESCRIPTION OF THE DRAWINGS

[025] The present technology is generally directed at methods for increasing a coal processing rate from coke ovens. One aspect of the present technology is to develop a control system so that a supply drawer dynamically supplies an oven in order to optimize the oven capacity, the coking process, the production yield and the quality of the coke. The control system allows each furnace to be supplied with a more uniform density which results in uniform temperature distribution in the furnace and better control of the coking cycle time. In some embodiments, a coal supply system includes a supply drawer in communication with a control system configured to automatically move the supply drawer. The automatic movement of the supply drawer can be based on maintaining a stable supply pressure (for example, chain pressure) simultaneously supplying coal in an oven or loading the oven according to an oven profile. Another aspect of this technology is to develop a dynamic leveling system. In some embodiments, the control system can be configured to automatically adjust the vertical height of the filling drawer to maintain an initial filling height or desired height of the filling drawer throughout the filling process. Another aspect of the present technology is to develop a scanning system used in conjunction with the control system. In some embodiments, the sweeping system is coupled to the supply drawer and is positioned to scan the oven floor to determine an oven capacity for coking and / or an oven floor profile. Using the specified oven capacity and / or oven floor profile, the control system is configured to automatically adjust its vertical position while supplying coal to the oven. Yet another aspect of the present technology is to determine the oven floor profile from a pusher drawer as the pusher drawer removes coke from an oven after it has been coked. Yet another aspect of the present technology is to reinforce the supply drawer to decrease the amount of fall from the distal end of the supply drawer. In some embodiments, the supply board is reinforced with the use of a combination of reinforcement plates, RIB support members and bearings.
[026] Specific details of several technology modalities are described below with reference to the Figures. Other details describing well-known structures and systems normally associated with pusher systems, supply systems and coke ovens have not been presented in the following disclosure to avoid unnecessarily obscuring the description of the various modalities of the technology. Many of the details, dimensions, angles, spatial orientation and other features shown in the Figures are merely illustrative of particular modes of technology. Consequently, other modalities can have other details, dimensions, angles, spatial orientation and resources without departing from the spirit or scope of the present technology. A person of ordinary skill in the art, therefore, will understand, therefore, that the technology may have other modalities with additional elements or the technology may have other modalities without several of the features shown and described below with reference to the Figures.
[027] Figure 1 depicts a modality of a pusher supplying machine (PCM) 100, which includes an operator cabin 116, an instrument housing 106, a main power transmission 110, a main frame 114, a storage drawer. pusher 102, a door extractor 104 and a hydraulic system 108. According to aspects of the disclosure, the PCM 100 is typically used for several different operations, including removing and replacing an oven door on the coal side, pushing a batch of coke supplied from the ovens, decarbonize the oven or supply coal in the ovens. According to one embodiment, a PCM operation sequence begins as the PCM 100 is moved along a set of tracks that operate in front of an oven battery for an assigned oven. The PCM 100 aligns your coal supply system to the oven and removes the oven door on the pusher side using the door extractor 104 from the coal supply system. The PCM 100 is then moved to align the pusher drawer 102 of the PCM 100 with the center of the oven and the pusher drawer 102 is energized to push coke out of the oven interior. The PCM 100 is moved again to align the coal supply system to the center of the furnace and coal is delivered to the PCM 100 coal supply system by a trigger conveyor. The coal supply system then supplies the coal inside the oven. The supply conveyor is then retracted from the oven from the same side as it was inserted. Finally, the door extractor 104 of the PCM 100 replaces and closes the oven door on the pusher side. Alternatively, a separate pusher and supply device can be used.
[028] Several modalities of the present technology are directed to supply the coal in the kiln to reach a constant thickness and constant density of coal in each kiln. Other modalities are directed to supply the coal in the kiln to reach a maximum amount of coal in each kiln. Therefore, the filling procedure is described in detail to better understand how the furnace supply is improved. In addition to the filling procedure described above, after the PCM 100 pushes the coke out of the oven, the PCM 100 will move to the right and align the coal supply system to the oven. According to one modality, once the alignment is completed, a false door will extend into the oven and the supply drawer will move into the oven. A supply delivery device, such as a conveyor or supply chain, moves forward to deliver coal from a trigger car to a feed hopper in the PCM and usually to the false door. The coal is supplied in the oven via the delivery device, as is the chain in the supply drawer. As coal is filled in the kiln, the level of coal in the kiln begins to increase. An operator can monitor and use a detected supply pressure (for example, chain pressure) from the supply drawer as an indication of the amount of coal that is filled in the furnace at a given position in the supply drawer. As the supply pressure increases, the operator can decrease the supply pressure and / or maintain the supply pressure at a desired pressure by manually moving the supply drawer from the opening on the pusher side of the oven towards the opening on the coke from the oven. The coal supply operation is manually controlled by the operator who counter, for example, a joystick in the operator's cabin 116.
[029] Figure 2 shows an exemplary process trend of an operator who manually supplies the oven. Line 220 indicates the position of the supply drawer as it moves from the pusher side towards the coke side of the oven. Line 230 indicates the supply pressure as the supply drawer moves from the coke side towards the pusher side of the oven. As shown, the supply drawer is moved approximately 1.52 to 4.57 meters (5 to 15 feet) inside the oven to an initial position when the supply drawer starts to fill the oven with charcoal. While in that initial position, supply pressure begins to develop. The slight drop of line 220 (between points 202 and 206) shows the supply drawer that drifts backwards due to the recoil through the chain tension as a result of the increasing supply pressure. Once the supply pressure develops to a predetermined pressure, the operator begins to move the supply drawer towards the opening on the coke side of the oven while filling the oven 206. The coal is loaded in the oven until the supply drawer fill reaches approximately the end of oven 210. During that fill time period, the operator is trying to maintain the fill pressure at approximately a predetermined set point. Throughout the supply, however, the supply pressure 230 fluctuates dramatically, as shown by the surrounding 208 at the time. In addition to the manual operation of the supply drawer by the operator, there are several factors that can vary the supply pressure in the supply process, including the inconsistent carbon level in the oven floor, the deflection and fall of the supply drawer, the moisture of coal and inconsistent furnace weight.
[030] Figure 3 is a schematic illustration of a coal supply system 300, configured according to the modalities of the present technology. The coal supply system 300 may include a plurality of horizontal coke ovens 304, a supply drawer 302 and a control system 340. The supply drawer 302 includes a proximal end portion 316 and a distal end portion 314 that comprises a vertically oriented supply drawer head 324. The supply drawer 302 also includes vertically oriented opposite sides 318 that span between the proximal end portions 316 and distal 314 of the supply drawer 302 and define a length of the supply drawer 302.
[031] Each oven 304 includes an opening on the pusher side 306, an opening on the coke side 308 opposite the opening on the pusher side 306 and opposite side walls 310 that together define an oven floor 312. Each oven 304 has an oven roof opposite oven floor 312. The opening on the pusher side 306 of oven 304 is the side through which the distal end portion 314 of the supply drawer 302 generally enters oven 304 to supply coal to the oven floor 312. The plurality of 304 ovens may include any bank of horizontal coke ovens, including, for example, heat recovery and non-heat recovery ovens. In some embodiments, the oven floor 312 is generally flat, as shown in Figure 3. In other embodiments, the oven floor 312 will not be flat and may include sloping surfaces (that is, upward, downward or downward). side), valleys, clods or accumulation of carbon material. The gas pipeline tunnels located below the oven floor 312 can also contribute to the unevenness of the oven floor 312.
[032] According to one embodiment of the disclosure, the coal supply system 300 also includes a rotary infinite conveyor system 330 operatively coupled to the supply drawer 302 and used to supply coal in oven 304. The conveyor system 330 includes an overhead and belt mechanism 332 coupled to gears 336 that are pivotally mounted to each of the opposite side walls 318 of the supply drawer 302. As the conveyor system 330 changes the coal in oven 304, the coal begins to develop to reach a lower level of the conveyor system 330 and eventually come into contact with the belt 332 of the conveyor system 330. The contact creates a drag force on the conveyor system 330 which results in what can be termed a supply pressure (for example , chain pressure). The supply pressure can be determined by a pressure sensor coupled to the supply drawer 302 and used as an implicit identification of how much coal has been filled in the furnace at a given position in the supply drawer 302.
[033] The coal supply system 300 also includes a control system 340 in communication with supply drawer 302 and used to control the movement of supply drawer 302 in and out of furnaces 304. The control system 340 it is also used for control and is in communication with the conveyor system 330. The control system 340 allows operators to control aspects of the PCM from a remote location. Many modalities of the 340 control system and / or technology described below can take the form of computer-executable instructions, including routines performed by a programmable computer. The control system 340 can also, for example, include a combination of supervisory control systems and data acquisition (SCADA), distributed control systems (DCS), programmable logic controllers (PLC), control devices and configured processors to process computer executable instructions. Individuals versed in the relevant technique will note that the technology can be practiced on computer systems other than those described in the present application. The technology can be embedded in a special-purpose computer or in a data processor that is specifically programmed, configured or built to perform one or more of the executable computer instructions described below. Consequently, the terms "control system" and "computer" as generally used in the present application refer to any data processor. The information handled by these computers can be displayed in any suitable display medium, including a CRT or LCD display.
[034] The technology can also be practiced in distributed environments, in which tasks or modules are performed by means of remote processing devices that are connected through a communications network. In a distributed computing environment, program modules or subroutines can be located on local and remote memory storage devices. The technology aspects described below can be stored or distributed on computer-readable media, including magnetic or optically readable or removable computer disks, as well as electronically distributed over networks. Data structures and data transmissions particular to aspects of technology are also covered by the scope of particular modalities of the revealed technology.
[035] In the present order, the control system 340 is configured to automatically move the supply drawer 302 (1) in a first direction generally along a z axis 350 between the opening on the coke side 308 and the opening on the pusher side 306 of the oven, (2) in a second direction generally along a geometry axis x 354 between opposite side walls 310 of the oven 304 and (3) in a third direction generally along a geometry axis y 352 between the oven floor 312 and oven roof 304 located opposite to oven floor 312. Control system 340 can also be configured to automatically move supply drawer 302 in a fourth generally rotatable direction 356 around the z-axis 350, twist the supply drawer 302 in a clockwise or counterclockwise direction, so that when the supply drawer 302 is twisted, one of the opposite side walls 318 of the supply drawer 30 2 is located higher or lower than the others within the opposite walls 318. In some embodiments, the control system 340 can also be configured to automatically move the supply drawer 302 in a generally rotatable fifth direction 358 around the geometric axis x 354, so that the distal end 314 of the supply drawer 302 can be angled upwards away from the oven floor 312 or downwards towards the oven floor 312. In some embodiments, the automatic movement of the supply drawer is determined at least in part by the supply pressure experienced by the conveyor system. Details of the 340 control system are described in more detail below. The movement of the supply drawer 302 in these directions can be done using a drive system that is operationally coupled to the supply drawer 302 and in communication with the control system 340. The drive system can include a hydraulic drive, an electric drive, a screw drive or other motif drivers as known in the art.
[036] Figure 4 is a block diagram of a 400 method for dynamically supplying a coal supply system according to technology modalities. In block 402, method 400 includes placing a supply drawer in an initial supply position of a coke oven. In some embodiments, the initial fill position includes at least one x and z coordinate position (that is, in the horizontal direction). In other embodiments, the initial fill position may include only a y coordinate position (that is, in the vertical direction) or a y coordinate position in addition to an x and z coordinate position. The positioning of the filling drawer in the initial filling position can also serve with a pre-requisite condition that needs to be met so that the control system 340 proceeds to step 404 and begins to perform the automatic function of filling oven 304. O positioning of the supply drawer 302 may also include locking the supply drawer 302 in the initial supply position to prevent the supply drawer 302 from migrating backwards towards the opening on the pusher side 306.
[037] In block 404, method 400 includes supplying coal in oven 304 in the initial supply position through conveyor system 330. Supplying coal in the oven includes loading coal into oven floor 312 and building a coal cake that exercises a supply pressure on the conveyor system 330. In some embodiments, the supply pressure may be required to reach a predefined lock pressure greater than 11.72 MPa (1,700 psi) before the locking mechanism releases the supply drawer from the initial supply position. In other embodiments, the locking pressure may need to develop to 20.68 MPa (3,000 psi) or greater before the locking mechanism is released. In particular, the control system can be programmed to automatically release the locking mechanism once the preset locking pressure is reached.
[038] In block 406, method 400 includes using a control system 340, automatically moving supply drawer 302 while simultaneously supplying coal in oven 304. Using a control system 340 may include using inputs for the control system 340 to dynamically fill oven 304. Entries for control system 340 may include those described below with reference to Figure 7. The automatic movement of supply drawer 302 may include reacting automatically to entries without manual intervention by the operator or beyond intervention manual by the operator. As previously mentioned, the movement of the supply drawer 302 may include moving the supply drawer 302 in at least one of (1) a first direction generally along a geometry axis z 350 between the opening on the coke side 308 and the opening on the pusher side 306 of the oven, (2) a second direction generally along a geometric axis x 354 between opposite side walls 310 of the oven 304, (3) a third direction generally along a geometric axis y 352 between the floor of oven 312 and the oven roof 304 located opposite to oven floor 312, (4) a fourth generally rotatable direction 356 around the z axis 350 and (5) a fifth generally rotatable direction 358 around an axis geometric parallel to the geometric axis x 354 and positioned at the proximal end 316 of the supply drawer 302. As such, the supply drawer 302 can be rotated so that the distal end 314 in a rotated state can be there located above or below the corresponding proximal end 315 of the supply drawer 302.
[039] In block 408, method 400 includes maintaining a supply pressure within a predefined operating range until the oven is completely filled. In some modalities, the predefined operational range of the supply pressure will be defined between 13.79 to 24.13 MPa (2,000 to 3,500 psi), while in other modalities the predefined operational range will be defined between 15,85 to 19,99 MPa (2,300 to 2,900 psi). In still other modalities, the predefined operational range will be defined even more narrowly between 17.23 to 18.61 MPa (2,500 to 2,700 psi). Maintaining the supply pressure may include maintaining the supply pressure by retaining the supply drawer in a given position to develop supply pressure, moving the supply drawer in a given direction to decrease the supply pressure or vary the rate of speed the supply drawer. In other modalities, the supply pressure will be maintained at a single point of definition entered by the operator.
[040] Figure 5 depicts a plot 500 of position test data from supply drawer 520 and pressure supply drawer 530 according to the present technology. As shown, plot 500 depicts how the supply pressure varies in relation to the position of the supply drawer (in the z 350 direction) during self-filling of an oven using the control system 340. According to the method described above with reference to Figure 2, since the PCM 100 pushes the coke out of oven 304, the PCM aligns the coal supply system to oven 304. At that point, the leveling setting of the supply drawer 302 can be adjusted (ie , raised or lowered) hydraulically. Once the level is set, the false door and supply drawer 302 will extend into oven 304. At point 502, supply drawer 302 is moved to the oven and stopped at an initial supply position to develop pressure from supply. In some embodiments, the supply drawer 302 will be locked in that initial supply position by means of the locking mechanism, which mechanically couples the supply drawer 302 to the PCM 100. This locking mechanism may prevent the supply drawer 302 from migrating to back towards the opening on the pusher side 306 as the furnace is filled, as shown previously in Figure 2. As shown by step 504, while in this starting position, coal is being filled in the oven floor 312 while the supply drawer is stationary and supply pressure begins to develop.
[041] Once a predefined supply pressure is reached, the control system 340 releases the locking mechanism and automatically starts to move the supply drawer 302. Each time the supply drawer 302 moves from a first position to a subsequent different second position, the supply pressure will decrease and then subsequently increase once the level develops in the second position. As previously mentioned, the supply pressure is used by the control system 340 as an implicit measure of how much coal is supplied in oven 312 at that particular position in the supply drawer 302. In this mode, this change in pressure is due to the fact that the The second position, towards the opening on the coke side or one of the opposite side walls or away from the oven floor, is a place in the oven that has less coal accumulation than was present in the first position. This movement is indicated by the stepped shape of the supply drawer position, as shown by step 506. As shown by step 508, a generally stable supply pressure during this supply period is maintained due to the continuous adjustment of the position control system supply drawer in response to the supply pressure variation.
[042] The stable supply pressure shown in Figure 5 compared to the variable supply pressure shown in Figure 2 is also due to other inherent advantages that the control system has manual control by an operator. The control system 340, for example, can include parameters, such as filter controller or derived integral proportional (PID) to anticipate and better adjust to the change in supply pressure. The control system 340 can also be specifically programmed for private ovens based on previous supplies from those ovens. Step 510 indicates that the supply drawer 302 reaches the end of the oven 304 and retracts back towards the opening on the pusher side 306 of the oven 304. As the supply drawer 302 is retracted back towards the opening on the side of the oven pusher 306 of oven 304, the supply pressure decreases.
[043] Although the position of the supply drawer 520 in Figure 5 generally refers to its horizontal position along the geometry axis z 350, the same principles apply to the movement of the supply drawer 302 along the geometric axis x 354 and the geometric axis y 352. For example, the movement from a first position to a subsequent second different position along the geometric axis x 354 or geometric axis y 352 will similarly decrease the supply pressure and then subsequently increase the supply pressure as the coal level develops in the second position.
[044] It is worth noting that the supply pressure is just a measure that can be used to determine the amount of coal that was supplied in oven 304 at a given position. In practice, any reactionary force, such as pressure or weight, or variable dimension, such as volume or height, that is created as a result of filling the oven 304 can also be used as the measure to determine the amount of coal supplied. For example, in other modalities, electrical signals (for example, power, tension, belt, etc.), optical signals (for example, lasers), visual signals (for example, cameras) or radio waves (for example, radar) they can also be used instead of or in addition to the supply pressure.
[045] Figure 6 is another schematic illustration of a coal supply system, configured according to the modalities of the present technology. Figure 6 has many features generally similar to those in Figure 3 described above. In particular, Figure 6 includes a scanning system 342 mechanically coupled to the supply drawer 302 and in electrical communication with the control system 340. In some embodiments, the scanning system 342 can instead be mounted on the supply head 324 or in the supply drawer frame 320. In still other embodiments, the scan system 342 can also be mounted on a PCM 100 structure different from the supply drawer 302. For example, the scan system 342 can be mounted in the drawer pusher 102 or any other structure that has a view of the oven floors 304.
[046] The 342 scanning system can include any device that is capable of capturing an image or assigning markers to a location. In some embodiments, the 342 scanning system will include a camera that is capable of capturing a 2-D or 3-D image of the 312 kiln floor. These cameras may include UV cameras, infrared cameras, high-speed cameras or other cameras. which include different spectra known in the art. Scanning system 342 can also include a plurality of lasers or radars that scan oven 302 and oven floor 312 to determine abnormalities or material that results in a non-uniform oven floor 312.
[047] One of the benefits of the 342 scanning system is to create a real-time loading map that can be used to ensure that a 304 oven is filled with a constant thickness throughout the 304 oven. A constant thickness throughout the 304 oven ensures that the quality of coke is maximized. In particular, the thickness of a coal bed is measured as the difference from the top of the supplied coal to the bottom of the supplied coal and is not necessarily measured from the top of the supplied coal to the end of the oven floor 312. If, for example, a remaining coke section remains in a 304 oven, the thickness measured for that section is the difference from the top of the carbon material to the bottom of the carbon material positioned immediately above that remaining coke. Consequently, scanning oven 304 may allow a coal supply system to locate uneven portions of oven floor 312 and proactively adjust the loading plane for that oven 304. For example, when loading a section of oven 304 that has a accumulation of material, the control system 312 can proactively adjust the supply drawer 302 in the vertical direction 352 in that section to ensure uniform thickness throughout the oven 304. Another benefit of the scanning system 342 is to create a loading map in real time which can be used to ensure that a 304 oven is filled with a varying thickness to maximize the amount of coal filled in the oven. This feature is described below with reference to Figure 6.
[048] As shown in Figure 6, scanning system 342 can design a virtual grid 344 on the oven floor 312. This virtual grid 344 can categorize each section of the oven floor 312 in an xz coordinate area or an area xyz coordinate. For example, grid 344 can divide and characterize oven floor 312 into a plurality of sections 346, so that each section 346 of grid 344 corresponds to an actual location of oven floor 312. Each section 346 can then be used to locate a relative location of remaining material 360 (for example coal, coke, clinker, coal test box, etc.) on the kiln floor. Virtual grid 344 in Figure 6 is represented by a 7 x 6 dimension comprising 42 separate sections 346. In other embodiments, virtual grid 344 can also be represented by a dimension comprising many more sections (that is, above 500 ) to obtain a more accurate 360 material relative location on the oven floor.
[049] In some embodiments, the scanning system 342 is configured to scan the oven floor 312 to determine any build-up (ie, material remaining 360) or unevenness in the oven floor. Each scan by the scan system 342 can generate an oven capacity, an oven floor profile and / or an oven profile for that particular oven. In other embodiments, the oven capacity, the oven floor profile and / or the oven profile can also be determined without the sweeping system. For example, pusher drawer 102, which pushes coke from oven 304, can also be used to develop the oven floor profile. When pusher drawer 102 pushes the filled coke from the opening on pusher side 306 of oven 304 towards the opening on coke side 308 of oven 304, pusher drawer 102 experiences a resistance that is based, at least in part, in the height and / or weight of the supplied coke bed, where a greater resistance implicitly indicates a thicker layer of coke supplied in that particular position. The variant resistance, which can be reflected in, for example, variation in a hydraulic or electrical signal, can then be used to create an oven profile to be used by the 340 control system to dynamically vary the height of the drawer. supply 302, as described above.
[050] In addition to the resistance experienced by pusher drawer 102, a self-leveling system can also be included in pusher drawer 102. Pusher drawer 102 can move dynamically in any direction (that is, along any of the axes geometry (xyz) and has skid shoes positioned behind the pusher drawer and in contact with the oven floor 312. Consequently, the oven floor profile can be captured and then transferred to the control system 340 for use during filling subsequent oven.
[051] Furnace capacity represents an estimate for the amount of coal that can be filled in the furnace in a single cycle. Oven capacity can be calculated using oven floor sweep 312 to determine a surface area of oven floor 312 that is covered by accumulation and then estimate a volume associated with the surface area. This estimated volume can then be subtracted from the design oven capacity for a particular oven.
[052] The oven floor profile quantifies variations in the oven floor 312. In addition to considering the remaining accumulation, the oven floor profile can also consider permanent accumulation, variation of oven construction, trenches, valleys, clods, etc. which can contribute to the variations or inequalities of the oven floor 312. After determining areas of inequality and assigning a location to those areas, using, for example, the virtual grid 346, the oven profile can create a loading map in time which can then be used to provide a height when supply drawer 302 needs to be in each section during subsequent fill. The scanning system 342 therefore allows the control system 340 to dynamically supply an oven 304 so that the thickness of the coal bed is constant throughout the process. For example, before filling an oven 304, scanning system 342 can scan oven floor 312 and determine which, if any, sections along the x-y coordinate area have an amount of carbon remaining. As shown in Figure 6, the remaining coke area and locations in sections A3 and C4 are translated into the control system 340. During a subsequent supply, the control system 340 can consider the xy coordinate to adjust its vertical movement and / or duration of time spent when the system is filling oven 304 at that particular xy coordinate. Proactive adjustment of these parameters, rather than just reactive, (for example in response to supply pressure) can further contribute to supplying each coal bed with a constant thickness and uniform density.
[053] In addition to scanning the oven floor 312, the scanning system 342 can also be used to scan a general oven 304 to create an oven profile. This can help determine other opportunities to supply additional coal in a 304 oven and achieve a maximum amount of coke with each oven cycle. For example, some ovens have ducts (ie, descent tubes) connected to the gas duct tunnels below oven floor 312 that are present on one or both of the opposite side walls 310 of oven 304. These descent tubes have openings that are commonly located approximately in the upper half of the side walls 310 of the oven 304. If the level of supplied carbon is greater than these open ends, the coal may fall into the descent tubes and block them. The scan system 342 can be used to identify the locations where these descent tubes are and the locations where these descent tubes are not. By knowing and translating these locations into the 340 control system, the 340 control system can avoid supplying coal in distinct areas adjacent to the downstream tube openings and can supply additional coal in those areas not adjacent to the downstream tube openings. . In this case, “adjacent” refers to the area surrounding the openings in the descent tubes where the supplied coal would fall into the openings in the descent tubes. Consequently, based on the furnace profile provided by the sweeping system 342, a furnace 304 can be filled to maximize its furnace capacity by supplying additional coal in areas not adjacent to the openings in the downpipes.
[054] The scanning system 342 can also be used to create an oven profile for a 304 oven after it has been loaded. For example, once an oven 304 is fully loaded, the supply drawer 302 retracts towards the opening on the pusher side 306 and exits oven 304 to start filling a subsequent oven. In some embodiments, the scanning system 342 can create an oven profile after supply drawer 302 leaves oven 304 and before it begins to fill the subsequent oven. This furnace profile represents an actual furnace profile, including the level or thickness of coal inside furnace 304, and can be used to adjust the method for filling that particular furnace with a subsequent load. For example, by knowing the oven floor profile before a 304 oven is filled and the actual oven profile after the 304 oven has been filled, an operator can continuously adjust the method for filling and know if the adjustments are leading to improvements. According to additional modalities, an oven 304 can be filled multiple times for a single cooking in that oven 304. For example, the control system 340 can be configured to scan oven 304 to generate a first oven floor and / or oven profile, fill oven 304 based on the oven floor and / or oven profile, retract supply drawer 302, scan oven 304 again to generate a second oven profile and supply additional coal in oven 304 to ensure that the coal has a constant thickness throughout oven 304 or to maximize the amount of coal in oven 304. The scanning system 342 can also be used to create an oven profile for a 304 oven and after it has been coking.
[055] Figure 7 depicts a schematic diagram illustrating several inputs 702 and outputs 704 for a control system 340 according to the present technology. Entries may include supply drawer position 706, supply pressure 708, furnace supply weight 710, furnace floor profile 712, preset operating pressure range 714, preset supply operating pressure 716, initial supply position 718 and oven profile 720. Using these inputs 702, the control system 340 can have multiple outputs 704 which include engaging / releasing the locking mechanism 720, adjusting the position of the supply drawer in a first horizontal direction 724, adjusting the position supply drawer in a second horizontal direction 726, adjust the supply drawer position in a third vertical direction 722, adjust the supply drawer position in the fourth and / or fifth swivel direction 728, start and / or stop supplying coal through the conveyor system 730 and adjust the coal supply rate through the conveyor system 732. This list of entries 702 is Outputs 704 is not intended to be completely comprehensive, as several other inputs to and from the control system 340 exist. Each input 702 and each output 704 can also represent an input from multiple sources. For example, the oven floor profile inlet 712 may represent an inlet of the scanning system 342 or of the pusher drawer heater 102, as described above. In addition, each input 702 can represent multiple inputs for the control system 340. For example, oven profile input 720 can have a first oven profile input from a 304 oven that has yet to be filled, a second oven input oven profile for a 304 oven that has already been filled and a third oven profile entry for a 304 oven that has already been filled and coked. In addition, each entry 702 can correspond to multiple exits 704. For example, an oven floor profile entry 712 can affect the position of the supply drawer in the vertical direction 722, the position of the supply drawer in the horizontal direction (front to back) ) 724 and the position of the supply drawer in the horizontal direction (side by side) 726.
[056] Figure 8 depicts a flow chart of a method for dynamically supplying a 304 oven from a coal supply system according to the present technology. Method 800 begins at decision block 802, where control system 340 determines whether supply drawer 302 is positioned in the initial supply position. As previously described, the initial fill position can correspond to a particular position along the x-z coordinate and / or a particular position along the y coordinate. This initial fill position will typically be defined by the operator. In some embodiments, for example, the initial filling position may be approximately 12.70 cm (five inches) after opening on the pusher side 306 of oven 304. If the control system 340 determines that the filling drawer 302 is not in the initial filling position, processing continues to block 804 where the control system 340 moves the filling drawer 302 to the initial filling position. Once the system determines that the supply drawer 302 is in the initial supply position, the method proceeds to block 806 and engages the locking mechanism to lock the supply drawer 302 in its initial supply position. Afterwards, the control system 340 proceeds to block 808 to start supplying coal in oven 304. As previously described, once the coal is supplied in oven 304, the supply pressure begins to develop. In decision block 810, control system 340 determines whether the supply pressure is above the predefined supply pressure. As previously mentioned, the predefined supply pressure will be set by the operator and, in some modalities, will be set to 15.86 MPa (2,300 psi). If the current supply pressure, as determined by the control system 340, is above the predefined supply pressure, then the control system 340 can automatically release the locking mechanism. If the current supply pressure is not above the predefined supply pressure, then the control system 340 may not automatically release the locking mechanism.
[057] Once the locking mechanism is released, method 800 proceeds to decision block 816, where control system 340 determines whether the supply pressure is above the predefined operational supply pressure. In some embodiments, the preset supply operating pressure will be equal to or slightly above the preset lock supply pressure. If the current supply pressure, as determined by the control system 340, is not above the predefined operational supply pressure, then the control system 340 can maintain its current position and wait for the supply pressure to continue to develop. If the current supply pressure is above the predefined operating operating pressure, then the control system 340 can automatically move the supply drawer 302 generally towards the opening on the coke side 308 of oven 304. The movement of the supply drawer 302 towards the opening on the coke side 308 may also include moving the supply drawer 302 towards the opposite side walls 310 of the oven 304 or moving the supply drawer away from the oven floor 312. Depending on the control system 340 moves supply drawer 302 automatically, decision block 822 determines whether oven 304 is fully filled. The control system 340 can determine that the oven 304 is fully filled if the supply drawer 302 is positioned in a defined position close to the opening on the coke side 308 of the oven. This position can be a manual entry by the operator or can be determined automatically by the control system 340. If the control system 340 determines that oven 304 is completely filled, the method ends. If control system 340 determines that furnace 304 is not fully filled, then control system 340 returns before decision block 816 above to determine whether the supply pressure as determined by the control system is above the operating pressure of predefined supply.
[058] Figures 9A to H depict side perspective views of a supply drawer 302 in various positions while supplying coal 394 in an oven 304 according to the present technology. More specifically, Figures 9A to D show the effect of the drop of the supply drawer (i.e., Si and S2) as the distal end 314 of the supply drawer 302 moves towards the opening on the coke side 308 of oven 304 and how the dynamic leveling capability of the 340 control system can address this problem. As shown in Figure 9A, supply drawer 302 enters the opening on the pusher side 306 of oven 304 at an initial fill height, h, and begins to supply coal 394 in oven 304. Figure 9B shows supply drawer 302 after having progressed further towards the opening on the coke side 308. Particularly, as the distal end 314 of the supply drawer 302 additionally extends away from the structural support (not shown) at the proximal end 316 of the supply drawer 302, where the distal end 314 of the supply drawer 302 begins to fall, Si, and is below the initial fill height, h. As a result, coal 384 is supplied below the initial fill height, h. Figure 9C shows the additional drop, S2, as the distal end 314 of the supply drawer 302 further extends to the oven 304. Figure 9D shows a generalized side perspective view of the supplied oven profile. In particular, the thickness of the coal bed 384 at the opening on the coke side 308 is significantly less than the thickness of the coal bed at the opening on the pusher side 306.
[059] Figures 9E to H show how the dynamic leveling capacity of the 340 control system can affect the furnace profile. Figure 9E, similarly to Figure 9A, shows the supply drawer 302 that enters the opening on the pusher side 306 of oven 304 and supplies coal 394 in oven 302 at the initial supply time, h. As the supply drawer 302 progresses towards the opening on the coke side 308, the dynamic leveling system automatically increases the distal end 314 of the supply drawer 302 to account for the expected supply drawdown (ie Si and S2) and maintaining the distal end 314 of the supply drawer 302 at the time of initial supply, h. As shown in Figure 9F, the supply drawer 302 is raised by a height equal to the drop Si in that particular supply drawer position. In some embodiments, the dynamic leveling capability of the control system 340 can ensure that the distal end 314 of the supply drawer 302 is at or near the initial fill height, by a sensor (not shown) communicating with the control system 340 which determines the height of the distal end 314 of the supply drawer 302. In other embodiments, the drop (i.e., Si and S2) of the supply drawer 302 in each distributed position is known and programmed in the control system 340 before supply starts. Figure 9G shows supply drawer 302 in an additional distributed position, where the dynamic leveling capability of the control system 340 elevated the proximal end 316 of supply drawer 302 by a height equal to the drop S2 to maintain the distal end 314 of the supply drawer 302 at the time of initial supply. Figure 9H shows a theoretical side perspective view of a profile with a constant thickness between the opening on the pusher side 306 and the opening on the coke side 308.
[060] In particular, the dynamic leveling capability of the control system 340 can also be used to adjust the height of the supply drawer 302 while the supply drawer 302 is being retracted from the oven back towards the pusher side 306 of the oven 304. As supply drawer 302 is retracted, supply drawer 302 can be raised to clean coal or adjusted to contact coal, so that coal is dragged back through supply drawer 302 to further adjust the distribute the coal evenly throughout the oven or to further maximize the amount of coal to be supplied. In some embodiments, the oven profile and / or the oven capacity used to supply the oven 304 can also be used during the retraction of the supply drawer 302 to further optimize the supply of each oven 304. The retraction of the supply drawer 302 is discussed in further detail below with reference to Figures 12 to 16.
[061] As previously described, one method to optimize dynamic filling in a coke oven is to use the automatic oven filling system, the sweeping system and / or the dynamic leveling system. Another method to optimize the supply is to mechanically reinforce the supply drawer to reduce the drop of the supply drawer. Referring later to Figures 10A and 10B, the supply drawer frame 320 includes a plurality of horizontally oriented support brackets 322 mechanically coupled to opposite sides 318 of the supply drawer 302. The supply drawer 302 itself is connected to and supported by PCM 100 at the proximal end 316, while the distal end 314 is floating freely. A purpose of the support clamps 322, therefore, is to maintain the structural integrity of the entire supply drawer 302. Support clamps 322 can be positioned normal or diagonally to the vertically oriented sides 318 of the supply drawer 302. In some embodiments, each support bracket 322 may be diamond-like in shape and arranged so that upper 388 and lower 386 portions of support bracket 322 represent top and bottom points of the diamond. In particular, the support clamps 322 are connected to the inner surface 376 on the sides of the supply drawer 302 and do not penetrate the outer surface 378 on the opposite sides 318 of the supply drawer 322. The support clamps 322 can also comprise a hollow bead and include an orifice opening 390 (Figure 11 A) drilled in the lower portion 386 of each support clamp 322. This is to ensure that fluid (eg, water) and gases are not trapped within the support clamp 322. According to Additional aspects of the development, the automatic furnace supply control system, the sweeping system and / or the dynamic leveling system can be combined with the mechanically reinforced supply drawer to further maximize the amount of coal, the density of coal or the uniformity of coal in the oven.
[062] As shown in Figure 10A, supply drawer 302 also includes a locking mechanism 348 attached to the proximal end 316 of supply drawer 302. Locking mechanism 348 can include a single male or female coupling or pair of couplings male or female which can be mechanically coupled to a corresponding coupling attached to a stationary structure of the PCM 100. As previously described, the locking mechanism 348 can prevent the supply drawer 302 from migrating backwards towards the opening on the pusher side 306 oven 304 during the initial filling process.
[063] Figure 10B depicts a top side perspective view of a modality of supply frame 320 with 386 bearings according to the present technology. Bearings 386 are fixed to upper portions 328 and lower 326 on opposite sides 318 of the supply drawer 302. Bearings 386 control and help to mechanically retain the distal end 314 of the supply drawer 302. Thus, the addition of a plurality of bearings in upper 328 and lower 326 portions on both opposite sides 318 can further decrease the drop of supply drawer 302 when extended.
[064] Each support bracket 322 provides additional structure support to further limit the fall of the supply frame 320 as the distal end 302 further extends away from the structural support of the PCM 100. To further limit this fall, additional structural supports can be coupled to each end of the crossed support clamps 322. Figures 11A and 11B depict a bottom side perspective view of a crossed clamp 322 supported by a reinforcement plate 370 and a support member of RIB 380 according to the present technology . Each reinforcement plate 370 is positioned between one end of a respective cross support clamp 322 and side 318 of the supply drawer 302. Reinforcement plate 370 thus surrounds at least a portion of the end of each support clamp 322. As such, the stress that results from loading the upper 388 and lower 386 portions of the diamond support bracket is distributed across the larger area of the reinforcement plate 370. The reinforcement plate 370 includes a mechanically coupled inner surface 372 (for example, example, welded) to the cross support bracket 322, as well as an outer-facing surface 374 that is opposite the inner-facing surface 372 and adhered to one side of the supply drawer 302. Reinforcement plate 370 can be made of any material steel or metal. In one embodiment, the reinforcement plate can have an overall length between 60.96 to 76.20 cm (24 to 30 inches), a height between 20.32 to 35.56 cm (8 to 14 inches) and a thickness between 1.27 / 2.54 cm (1/2 to 1 inch). In other embodiments, these dimensions may vary depending on the surface area of the end of the support clamp 322 and the side walls 310 of the supply drawer 302.
[065] RIB 380 support members are also included to provide additional mechanical support for each cross support clamp 322. Specifically, the diamond-shaped support clamps 322 and the coupling arrangement to the side walls 318 of the supply drawer 302 result in additional weight in the lower portion 386, or in the bottom corner, of the support clamp 322. The support of RIB 380 helps to distribute the load and increase the welded length of that area. Each support member of RIB 380 is therefore positioned in a lower portion 386 of support clamps 322, so that a first surface 382 of the support member of RIB 380 is mechanically coupled to the surface facing inward 372 of the support plate. reinforcement 370 and a second surface 384 of the support member 380 is mechanically coupled to the lower portion 386 of the support clamp 322. The support member of RIB 380 can be composed of material similar to that of the reinforcement plate 370.
[066] The data taken during the testing of installed reinforcement plates 370 and support members RIB 380 indicate a dramatic improvement in the amount of stress experienced by support bracket 322. For example, the maximum stress displayed on an interior surface 372 of the walls opposite sides 318 of supply drawer 302 next to a lower portion 386 of support clamp 322 without reinforcement plate 370 or RIB support 380 was beyond 23.44 MPa (3,400 psi). The maximum stress displayed on a lower portion 386 of the support bracket 322 with the reinforcement plate 370 decreases to approximately 12 MPa (1,740 psi) and further decreases to approximately 11.48 MPa (1,665 psi) with the support of RIB 380. Tests similar on an outer surface 378 of the opposite side walls 318 of the supply drawer 302 near the lower portion 386 of the support clamp 322 show a maximum stress of 34.47 MPa (5,000 psi) without a reinforcement plate 370 or a RIB support 380, 24.71 MPa (3,585 psi) with the 370 reinforcement plate and 24.33 MPa (3,530 psi) with the 370 reinforcement plate and the RIB 380 support. This improvement of approximately 40% in decreased maximum stress was consistent for all the different experimental analysis tests.
[067] Figure 12 depicts a front perspective view of a supply frame modality 320 and a supply head 604 of a coal supply system according to the present technology. In various embodiments, the supply head 604 is defined by a flat body 614, which has an upper edge portion 616, a lower edge portion 618, opposite side portions 620 and 622, a front face 624 and a rear face 626. In some embodiments, a substantial portion of the body 614 resides within a supply head plane. This is not to suggest that modalities of the present technology will not supply supply head bodies that have aspects that occupy one or more additional plans. In several modalities, the flat body is formed from a plurality of tubes, which have square or rectangular cross-sectional shapes. In particular modalities, the tubes have a width of 15.24 cm (six inches) to 30.48 cm (twelve inches). In at least one embodiment, the tubes are 20.32 cm (eight inches) wide, which has demonstrated significant resistance to warping during supply operations. Many of the features described in relation to the supply head 604 can be shared with the supply head 324 described above.
[068] Various embodiments of the supply head 604 include a pair of opposite wings 628 and 630 that are shaped to have free end portions 632 and 634. In some embodiments, the free end portions 632 and 634 are positioned in a spaced relationship forward from the supply head plane. In particular embodiments, the free end portions 632 and 634 are spaced forward from the supply head plane by a distance of 15.24 to 60.96 cm (six inches to 24 inches), depending on the size of the supply head. supply 604 and the geometry of the opposite wings 628 and 630. In this position, the opposite wings 628 and 630 define open spaces behind from the opposite wings 628 and 630, through the supply head plane. As the design of these open spaces increases in size, more material is distributed to the sides of the coal bed. As spaces are made smaller, less material is distributed to the sides of the coal bed. Consequently, the present technology is adaptable according to particular characteristics presented from coking system to coking system.
[069] In some embodiments, as depicted in Figures 13A to 13C, the opposing wings 628 and 660 include first faces 636 and 638 that extend outwardly from the supply head plane. In particular embodiments, the first faces 636 and 638 extend outwardly from the supply plane at an angle of forty-five degrees. The angle at which the first face deviates from the supply head plane can be increased or decreased according to the particular intended use of the coal supply system 300. For example, particular embodiments can employ an angle of ten degrees to sixty degrees , depending on the anticipated conditions during supply and leveling operations. In some embodiments, the opposing wings 628 and 630 additionally include second faces 640 and 642 extending outwardly from the first faces 636 and 638 towards the free distal end portions 632 and 634. In particular embodiments, the second faces 640 and 642 of the opposite wings 628 and 630 reside on a wing plane that is parallel to the supply head plane. In some embodiments, the second faces 640 and 642 are provided to be approximately 25.4 cm (ten inches) in length. In other embodiments, however, the second faces 640 and 642 can have lengths in the range 0 to 25.4 cm (zero to ten inches), depending on one or more design considerations, including the length selected for the first faces 636 and 638 and the angles at which the first faces 636 and 638 extend away from the supply plane. As shown in Figures 13A to 13C, the opposing wings 628 and 630 are shaped to receive loose coal from the rear face of the supply head 604, while the coal supply system 300 is being removed by the entire coal bed that is supplied, and tapering or otherwise directing loose coal towards the side edges of the coal bed. At least in this way, the coal supply system 300 can reduce the likelihood of voids on the sides of the coal bed. Instead, wings 628 and 630 help promote the level of the coal bed previously described. The test showed that the use of the opposite wings 628 and 630 can increase the supply weight by only one to two tons, filling these side voids. In addition, the shape of the wings 628 and 630 reduces charcoal recoil and spillage on the pusher side of the oven, which reduces waste and labor costs to recover spilled coal.
[070] With reference to Figure 14, several modalities of the present technology position an extrusion plate 666 operationally coupled to the rear face 626 of the supply head 324. In some embodiments, the extrusion plate 666 includes a coal engaging face 668 that it is oriented to face backwards and downwards in relation to supply head 604. In this way, loose coal that is supplied in the furnace behind supply head 604 will engage with the coal engaging face 668 of extrusion plate 666. Due As the coal pressure is deposited behind the supply head 604, the coal engagement face 668 compacts the coal downwards, increasing the coal density of the coal bed under the extrusion plate 666. In several embodiments, the coal plate extrusion 666 extends substantially along a length of the supply head 604 in order to maximize density across a significant width of the carbon bed. With continuous reference to Figures 15 and 16, the extrusion plate 666 additionally includes an upper deflection face 670 which is oriented to face backwards and upwards in relation to the supply head 604. Thus, the coal engaging face 668 and the upper deflection face 670 are coupled together to define a peak shape, which has a peak ridge that faces back away from the supply head 604. Consequently, any coal that falls on the upper deflection face 670 will be directed out of the extrusion plate 666 to join the incoming coal before it is extruded.
[071] In use, the coal is shuffled to the front end portion of the coal supply system 300, behind the supply head 604. The coal accumulates in the opening between the conveyor and the supply head 604 and the pressure of conveyor supply begins to develop gradually until it reaches approximately 17.23 to 19.30 MPa (2,500 to 2,800 psi). Referring to Figure 15, the coal is fed into the system behind the supply head 604 and the supply head 604 is retracted back through the furnace. The 666 extrusion plate compacts the coal and extrudes it into the coal bed.
[072] Figure 16 depicts the effect on the density of a coal supply with the benefit of the 666 extrusion plate (left side of the coal bed) and without the benefit of the 666 extrusion plate (right side of the coal bed). As depicted, the use of extrusion plate 666 provides an area of increased density of apparent carbon bed "D" and an area of apparent density of reduced coal bed "d", where the extrusion plate is not present. In this way, the 666 extrusion plate not only demonstrates an improvement in surface density, but also improves the apparent density of the overall internal bed.
[073] The test results, shown in Figures 17 and 18 below, show the improvement of bed density with the use of the 666 extrusion plate (Figure 18) and without the use of the 666 extrusion plate (Figure 17). The data demonstrates a significant impact on both surface density and 60.96 cm (twenty-four inches) below the surface of the coal bed. In some tests, an extrusion plate 666 that has a peak of 25.4 cm (ten inches) (distance from the rear of the supply head 604 to the peak crest of the extrusion plate 666, on which the coal engaging face 668 and the upper deflection face 670 meet). In other tests, in which a 15.24 cm (six inch) peak was used, the carbon density was increased, but not to the levels that result from using the 25.4 cm (ten inch) extrusion plate 666 The data reveal that the use of the 25.4 cm (ten inch) extrusion plate increased the density of the coal bed, which allowed an increase in the supply weight of approximately two and a half tons.
