    [001]This application claims priority benefit to U.S. Provisional Patent Application Serial No. 62/043,359, filed August 28, 2014, the disclosure of which is incorporated herein in its entirety by reference. FIELD OF TECHNIQUE
    [002] The present technology is, in general, directed to coke oven loading systems and methods of use. BACKGROUND
    [003] Coke is a solid carbon fuel and carbon source used to smelt and reduce iron ore in steel production. In one 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 twenty-four to forty-eight hours under closely controlled atmospheric conditions. . Coke ovens have been used for many years to convert coal into metallurgical coke. During the coking process, the finely crushed coal is heated under controlled temperature conditions to devolatilize the coal and form a coke melt that has a predetermined porosity and strength. Due to the fact that coke production is a batch process, multiple coke ovens are operated simultaneously.
    [004] Most of the coke making process is automated due to the extreme temperatures involved. For example, a push loader (“PCM”) is typically used on the coal side of the kiln for a number of different operations. A common PCM operating sequence begins as the PCM is moved along a set of rails that run in front of a kiln battery to an assigned kiln and align a PCM coal loading system with the kiln. The push-side oven door is removed from the oven using a door puller from the coal loading system. The PCM is then moved to align a PCM pusher plunger with the center of the oven. The pusher plunger is energized to push the coke from inside the oven. The PCM is again moved away from the center of the kiln to align the coal loading system with the center of the kiln. Coal is delivered to the PCM coal loading system by an unloading conductor. The coal loading system then loads the coal inside the kiln. In some systems, particulate matter trapped in hot gas emissions escaping from the furnace face is captured by the PCM during the coal loading step. In such systems, particulate matter is extracted in an emissions dome through the filter bag chamber of a dust collector. The charging conductor is then retracted from the furnace. Finally, the PCM door puller replaces and locks the oven door on the push side.
    [005]Referring to Figure 1, PCM coal loading systems 10 have commonly included an elongated frame 12 that is mounted on the PCM (not shown) and reciprocally movable, toward and away from coke ovens. A flat loading head 14 is positioned at a free distal end of the elongate frame 12. A conductor 16 is positioned within the elongate frame 12 and extends substantially along a length of the elongate frame 12. The loading head 14 is used , in a reciprocating motion, to generally level the coal that is deposited in the kiln. However, with reference to Figures 2A, 3A and 4A, prior art coal loading systems tend to leave voids 16 on the sides of the coal bed, as shown in Figure 2A, and hollow depressions in the surface of the coal bed. These voids limit the amount of coal that can be processed by the coke oven for a coke cycle time (coal processing rate), which, in general, reduces the amount of coke produced by the coke oven by the coke cycle. (coke production rate). Figure 2B shows the manner in which an ideally loaded level coke bed would look.
    [006]The weight of coal loading system 10, which may include internal water cooling systems, may be 36 tonnes (80,000 pounds) or more. When the loading system 10 is extended into the furnace during a loading operation, the coal loading system 10 deflects downwardly at its free distal end. This shortens the coal carrying capacity. Figure 3A indicates the drop in bed height caused by the deflections of the coal loading system 10. The graph shown in Figure 5 shows the coal bed profile along the length of the kiln. The bed height drop, due to the deflection of the coal loading system, is twelve to twenty centimeters (five inches to eight inches) from the push side to the coke side, depending on the load weight. As shown, the effect of deflection is more significant when less coal is loaded into the kiln. In general, deflection of the coal loading system can cause a loss of coal volume of approximately one to two tons. Figure 3B shows the manner in which an ideally loaded level coke bed would look.
    [007] Despite the deflection effect of the coal loading system caused by its weight and cantilevered position, the coal loading system 10 provides little benefit in the sense of coal bed densification. Referring to Figure 4A, the coal loading system 10 provides minimal improvement in the internal coal bed density, forming a first layer d1 and a less dense second layer d2 at the bottom of the coal bed. Increasing the coal bed density can facilitate conductive heat transfer throughout the coal bed which is a component in determining kiln cycle time and kiln production capacity. Figure 6 shows a set of density measurements taken for a furnace test using a prior art coal loading system 10. The line with diamond indicators shows the density at the surface of the coal bed. The line with the square indicators and the line with the triangular indicators show the density of thirty to sixty-one centimeters (twelve inches and twenty-four inches) below the surface, respectively. The data demonstrate that the bed density drops more on the coke side. Figure 4B shows the manner in which an ideally loaded level coke bed would appear, having layers D1 and D2 of relatively increased density. BRIEF DESCRIPTION OF THE DRAWINGS

    [051] The present technology is generally aimed at coal loading systems used with coke ovens. In various embodiments, coal loading systems of the present technology are configured for use with horizontal heat recovery coke ovens. However, embodiments of the present technology can be used with other coke ovens, such as horizontal ovens without recovery. In some embodiments, a coal loading system includes a loading head that has opposing wings that extend outward and forward from the loading head, leaving an open path through which coal can be directed to the side edges of the vessel. coal bed. In other embodiments, an extrusion plate is positioned on a back face of the loading head and oriented to engage and compress the coal as the coal is loaded along a length of the coking oven. In still other embodiments, a false door is vertically oriented to maximize the amount of coal that is loaded into the kiln.
    [052] Specific details of various embodiments of the technology are described below with reference to Figures 7 to 29. Other details describing well-known structures and systems often associated with pusher systems, loading systems and coke ovens have not been presented in the following disclosure to avoid unnecessary concealment of the description of the various modalities of the technology. Many of the details, dimensions, angles and other features shown in the Figures are merely illustrative of particular modalities of the technology. Consequently, other modalities may have other details, dimensions, angles and features without departing from the spirit or scope of the present technology. An element of common knowledge in the art, therefore, will accordingly understand that the technology may have other embodiments with additional elements, or the technology may have other embodiments without several of the features shown and described below with reference to Figures 7 to 29.
    [053] It is contemplated that the coal loading technology of the present subject will be used in combination with a push loader (“PCM”) that has one or more other components common to PCMs, such as a port extractor, a plunger pusher, an unloading conductor and the like. However, aspects of the present technology can be used separately from a PCM and can be used individually or with other equipment associated with a coking system. Consequently, aspects of the present technology can be simply described as “a coal loading system” or components thereof. The components associated with coal loading systems such as coal conductors and the like that are well known may not be described in detail, if in fact to avoid unnecessary concealment of the description of the various modalities of the technology.
    [054] Referring to Figures 7 to 9C, a coal loading system 100 is shown, having an elongated loading frame 102 and a loading head 104. In various embodiments, the loading frame 102 will be configured to have opposite sides. 106 and 108 that extend between a distal end portion 110 and the proximal end portion 112. In various applications, the proximal end portion 112 may be coupled to a PCM in a manner that allows selective extension and retraction of the frame. loading 102 into and from the interior of a coke oven during a coal loading operation. Other systems, such as a height adjustment system that selectively adjusts the height of the loading frame 102 in relation to a coke oven floor and/or a coal bed, may also be associated with the coal loading system 100.
    [055]Load head 104 is coupled to distal end portion 110 of elongate loading frame 102. In various embodiments, loading head 104 is defined by a flat body 114, which has an upper edge portion 116, a bottom edge portion 118, opposing side portions 120 and 122, a front face 124 and a rear face 126. In some embodiments, a substantial portion of the body 114 resides within a loading head plane. This is not to suggest that embodiments of the present technology will not provide loading head bodies that have aspects that occupy one or more additional planes. In various embodiments, the flat body is formed from a plurality of tubes, which have square or rectangular cross-sectional shapes. In particular embodiments, the tubes are fifteen to thirty centimeters (six inches to twelve inches) wide. In at least one embodiment, the tubes are twenty centimeters (eight inches) wide, which has demonstrated significant resistance to buckling during loading operations.
    [056] In further reference to Figures 9A through 9C, various embodiments of the loading head 104 include a pair of opposing wings 128 and 130 that are shaped to have free end portions 132 and 134. In some embodiments, the free end portions 132 and 134 are positioned in a separate relationship, forward from the loading head plane. In particular embodiments, the free end portions 132 and 134 are spaced forward from the loading head plane by a distance of fifteen to 61 centimeters (six inches to 24 inches), depending on the size of the loading head 104 and the geometry of the opposing wings 128 and 130. In this position, the opposing wings 128 and 130 define spaces open back from the opposing wings 128 and 130, across the loading head plane. As the design of these open spaces is increased in size, more material is distributed to the sides of the coal bed. As spaces become smaller, less material is distributed to the sides of the coal bed. Consequently, the present technology is adaptable as particular characteristics are presented from the coking system to the coking system.
    [057] In some embodiments, as shown in Figures 9A to 9C, opposing wings 128 and 130 include first faces 136 and 138 that extend outward from the loading head plane. In particular embodiments, first faces 136 and 138 extend outward from the loading plane at a forty-five degree angle. The angle at which the first face deviates from the loading head plane may be increased or decreased according to the particular intended use of the coal loading system 100. For example, particular embodiments may employ an angle of ten degrees to sixty degrees. , depending on anticipated conditions during loading and leveling operations. In some embodiments, opposing wings 128 and 130 additionally include second faces 140 and 142 extending outwardly from first faces 136 and 138 toward free distal end portions 132 and 134. In particular embodiments, second faces 140 and 142 of the opposing wings 128 and 130 reside within a wing plane that is parallel to the loading head plane. In some embodiments, the second faces 140 and 142 are provided to be approximately twenty-five centimeters (ten inches) in length. In other embodiments, however, the second faces 140 and 142 may have lengths in the range of zero to twenty-five centimeters (zero to ten inches), depending on one or more design considerations, including the length selected for the first ones. faces 136 and 138 and the angles at which the first faces 136 and 138 extend away from the loading plane. As shown in Figures 9A to 9C, the opposing wings 128 and 130 are shaped to receive loose coal from the rear face of the loading head 104 while the coal loading system 100 is being withdrawn through the coal bed being loaded, and passes through the funnel or otherwise directs loose coal towards the side edges of the coal bed. At least in this way, the coal loading system 100 can reduce the likelihood of voids on the sides of the coal bed, as shown in Figure 2A. Preferably, wings 128 and 130 help to promote the level coal bed shown in Figure 2B. Testing has shown that the use of the 128 and 130 opposing wings can increase the payload weight by one to two tons by filling these side voids. In addition, the shape of the wings 128 and 130 reduces coal drag and spillage from the kiln pusher side, which reduces waste and labor costs to recover spilled coal.
    [058] Referring to Figures 10A to 10C, another embodiment of a loading head 204 is shown as having a flat body 214 having an upper edge portion 216, a lower edge portion 218, opposing side portions 220 and 222, a front face 224 and a rear face 226. The loading head 204 further includes a pair of opposing wings 228 and 230 that are shaped to have free end portions 232 and 234 that are positioned in separate relationship, facing forward. from the loading head plane. In particular embodiments, the free end portions 232 and 234 are spaced forward from the loading head plane by a distance of fifteen to 61 centimeters (six inches to 24 inches). Opposite wings 228 and 230 define spaces open back from opposing wings 228 and 230 through the loading head plane. In some embodiments, opposing wings 228 and 230 include first faces 236 and 238 that extend outward from the loading head plane at a forty-five degree angle. In particular embodiments, the angle at which first faces 236 and 238 deviate from the loading head plane is from ten degrees to sixty degrees, depending on anticipated conditions during loading and leveling operations. Opposite wings 228 and 230 are shaped to receive loose coal from the back face of loading head 204 while the coal loading system is being drawn through the coal bed being loaded, and passed through the hopper or otherwise directs loose coal towards the lateral edges of the coal bed.
    [059] Referring to Figures 11A to 11C, a further embodiment of a loading head 304 is shown as having a flat body 314, which has an upper edge portion 316, a lower edge portion 318, opposing side portions 320 and 322, a front face 324 and a rear face 326. The loading head 300 further includes a pair of opposing curved wings 328 and 330 which have free end portions 332 and 334 that are positioned in separate relationship, forward from the loading head plan. In particular embodiments, the free end portions 332 and 334 are spaced forward from the loading head plane by a distance of fifteen to sixty-one centimeters (six inches to twenty-four inches). Opposite curved wings 328 and 330 define spaces open back from opposing curved wings 328 and 330 through the loading head plane. In some embodiments, the opposing curved wings 328 and 330 include first faces 336 and 338 that extend outwardly from the loading head plane at a forty-five degree angle from a proximal end portion of the opposing curved wings. 328 and 330. In particular embodiments, the angle at which first faces 336 and 338 deviate from the loading head plane is from ten degrees to sixty degrees. This angle dynamically changes along the lengths of the opposing curved wings 328 and 330. Opposite wings 328 and 330 receive loose coal from the rear face of the loading head 304 while the coal loading system is being withdrawn through the coal bed. which is loaded, and passes through the funnel or otherwise directs the loose coal towards the side edges of the coal bed.
    [060] Referring to Figures 12A to 12C, one embodiment of a loading head 404 includes a flat body 414 having an upper edge portion 416, a lower edge portion 418, opposite side portions 420 and 422, a face front face 424 and a rear face 426. Loading head 400 further includes a first pair of opposing wings 428 and 430 which have free end portions 432 and 434 that are positioned in separate relationship, forward from the head plane of loading. Opposite wings 428 and 430 include first faces 436 and 438 extending outwardly from the loading head plane. In some embodiments, first faces 436 and 438 extend outward from the loading head plane at a forty-five degree angle. The angle at which the first face deviates from the loading head plane may be increased or decreased according to the particular intended use of the coal loading system 400. For example, particular embodiments may employ an angle of ten degrees to sixty degrees. , depending on anticipated conditions during loading and leveling operations. In some embodiments, the free end portions 432 and 434 are spaced forward from the loading head plane by a distance of fifteen to sixty-one centimeters (six inches to twenty-four inches). Opposite wings 428 and 430 define spaces open back from opposing curved wings 428 and 430 through the loading head plane. In some embodiments, opposing wings 428 and 430 additionally include second faces 440 and 442 extending outwardly from first faces 436 and 438 toward free distal end portions 432 and 434. In particular embodiments, second faces 440 and 442 of the opposing wings 428 and 430 reside within a wing plane that is parallel to the loading head plane. In some embodiments, the second faces 440 and 442 are provided to be approximately twenty-five centimeters (ten inches) in length. In other embodiments, however, the second faces 440 and 442 may have lengths in the range of zero to twenty-five centimeters (zero to ten inches), depending on one or more design considerations, including the length selected for the first ones. faces 436 and 438 and the angles at which the first faces 436 and 438 extend away from the loading plane. Opposite wings 428 and 430 are shaped to receive loose coal from the rear face of loading head 404, while coal loading system 400 is being withdrawn through the coal bed being loaded, and passed through the hopper or otherwise , directs loose coal towards the lateral edges of the coal bed.
    [061] In various embodiments, it is contemplated that opposing wings of various geometries may extend rearwardly from a loading head associated with a coal loading system in accordance with the present technology. With continued reference to Figures 12A through 12C, the loading head 400 additionally includes a second pair of opposing wings 444 and 446 that include free end portions 448 and 450 that are positioned in separate relationship, rearwardly from the head plane. loading. Opposite wings 444 and 446 include first faces 452 and 454 that extend outwardly from the loading head plane. In some embodiments, the first faces 452 and 454 extend outward from the loading head plane at a forty-five degree angle. The angle at which the first faces 452 and 454 deviate from the loading head plane may be increased or decreased according to the particular intended use of the coal loading system 400. For example, particular embodiments may employ a ten degree angle. to sixty degrees, depending on conditions anticipated during loading and leveling operations. In some embodiments, the free end portions 448 and 450 are spaced rearwardly from the loading head plane by a distance of fifteen to sixty-one centimeters (six inches to twenty-four inches). Opposite wings 444 and 446 define spaces open back from opposing wings 444 and 446 through the loading head plane. In some embodiments, opposing wings 444 and 446 additionally include second faces 456 and 458 extending outwardly from first faces 452 and 454 toward free distal end portions 448 and 450. In particular embodiments, second faces 456 and 458 of the opposing wings 444 and 446 reside within a wing plane that is parallel to the loading head plane. In some embodiments, the second faces 456 and 458 are provided to be approximately twenty-five centimeters (ten inches) in length. In other embodiments, however, the second faces 456 and 458 may have lengths in the range of zero to twenty-five centimeters (zero to ten inches), depending on one or more design considerations, including the length selected for the first ones. faces 452 and 454 and the angles at which first faces 452 and 454 extend away from the loading plane. The opposing wings 444 and 446 are shaped to receive loose coal from the front face 424 of the loading head 404, while the coal loading system 400 is being extended along the bed of coal being loaded, and passing through the hopper or, otherwise, they direct loose coal towards the lateral edges of the coal bed.
    [062]In continued reference to Figures 12A to 12C, the opposing rearward-facing wings 444 and 446 are shown as being positioned above the opposing forward-facing wings 428 and 430. However, it is contemplated that this particular arrangement may be reversed, in some modalities, without departing from the scope of the present technology. Similarly, the opposing rearward facing wings 444 and 446 and the opposing forward facing wings 428 and 430 are shown as angularly arranged wings having first and second sets of faces that are disposed at angles to each other. However, it is contemplated that one or both sets of opposing wings may be provided in different geometries, as demonstrated by the angularly arranged straight opposing wings 228 and 230, or the curved wings 328 and 330. Other known shape combinations, intermixed or in pairs, are contemplated. Furthermore, it is further contemplated that the loading heads of the present technology could be provided with one or more sets of opposing wings that face only rearwardly from the loading head, with no wings facing forward. In such cases, the opposite wings positioned aft will distribute the coal to the lateral portions of the coal bed when the coal loading system is moving forward (loading).
    [063]Referring to Figure 13, it is contemplated that as the coal is being loaded into the furnace and as the coal loading system 100 (or similarly, the loading heads 200, 300, or 400) is being withdrawn through the coal bed, the loose coal may begin to pile up over the upper edge portion 116 of the loading head 104. Accordingly, some embodiments of the present technology will include one or more angularly arranged particulate deflection surfaces 144 on top of the upper edge portion 116 of loading head 104. In the example shown, a pair of oppositely facing particulate deflection surfaces 144 combine to form a spiked structure which disperses wrong particulate material in front of and behind the loading head 104 It is contemplated that it may be desirable, in particular cases, to have the particulate matter contact area primarily in front of or behind the loading head then 104, but not both. Consequently, in such cases, a single particulate deflection surface 144 can be provided with a chosen orientation to disperse the coal accordingly. It is further contemplated that the particulate deflection surfaces 144 may be provided in other non-planar or non-angled configurations. In particular, the particulate deflection surfaces 144 can be planar, curvilinear, convex, concave, composite, or various combinations thereof. Some embodiments will merely arrange the particulate deflection surfaces 144 so that they are not horizontally arranged. In some embodiments, the particulate surfaces may be integrally formed with the upper edge portion 116 of the loading head 104, which may additionally include a water cooling feature.
    [064] The bulk density of the coal bed plays a significant role in determining coke quality and minimizing burn-off loss, particularly close to the furnace walls. During a coal loading operation, the loading head 104 retracts against a top portion of the coal bed. In this way, the loading head contributes to the superior shape of the coal bed. However, the particular aspects of the present technology cause the loading head portions to increase the density of the coal bed. Referring to Figures 14 and 15, the opposing wings 128 and 130 may be provided with one or more elongate densifying bars 146 which, in some embodiments, extend along a length of and downward from each other. of opposing wings 128 and 130. In some embodiments, as shown in Figures 14 and 15, the densification bars 146 may extend downwardly from bottom surfaces of opposing wings 128 and 130. In other embodiments, as shown in Figure 16, the densification bars 146 may be operatively coupled to the rear or front faces of one or both of the opposing wings 128 and 130 and/or the lower edge portion 118 of the loading head 104. In particular embodiments, as shown in Fig. Figure 14 , elongate densification bar 146 has a long axis arranged at an angle to the loading head plane. It is contemplated that the densification bar 146 may be formed from a roller which rotates about a generally horizontal axis, or a statically mounted structure of various shapes, such as a tube or rod, formed from a material high temperature. The outer shape of the elongated densification bar 146 may be flat or curvilinear. In addition, the elongated densification bar may be curved along its length or angled.
    [065] In some embodiments, the loading heads and loading frames of various systems may not include a cooling system. The extreme temperatures of the ovens will cause portions of such loading heads and loading frames to expand slightly, and at different rates, relative to each other. In such embodiments, rapid and uneven expansion and heating of components can stress the coal loading system and warp or otherwise misalign the loading head with respect to the loading frame. Referring to Figures 17 and 18, embodiments of the present technology couple the loading head 104 to the sides 106 and 108 of the loading frame 102 using a plurality of grooved gaskets that allow relative movement between the loading head 104 and elongate loading frame 102. In at least one embodiment, first frame plates 150 extend outwardly from inner faces of sides 106 and 108 of elongate frame 102. First frame plates 150 include one or more elongated mounting slots 152 that penetrate first frame plates 150. In some embodiments, second frame plates 154 are also provided to extend outwardly from the inner faces of sides 106 and 108 below first frame plates 150 The second frame plates 154 of the elongate frame 102 also include one or more elongate mounting slots 152 that penetrate the second frame plates 154. Head lacquers 156 extend outward from opposite sides of the back face 126 of loading head 104. First head plates 156 include one or more mounting apertures 158 that penetrate first head plates 156. In some embodiments, second head plates 160 are also provided to extend outwardly from rear face 126 of loading head 104 below first head plates 156. Second head plates 160 also include one or more mounting apertures 158 which penetrate the second head plates 158. The loading head 104 is aligned with the loading frame 102 so that the first frame plates 150 align with the first head plates 156 and the second frame plates 154 align with the second head plates 160. Mechanical latches 161 pass through elongated mounting slots 152 of first frame plates 150 and second frame plates 152 and openings corresponding mounting slots 160. In this manner, the mechanical latches 161 are placed in a fixed position with respect to the mounting openings 160, but allowed to move along the lengths of the elongated mounting slots 152 in accordance with the mounting head 160. loading 104 moves relative to loading frame 102. Depending on the size and configuration of loading head 104 and elongated loading frame 102, it is contemplated that more or less loading head plates and frame plates of various shapes and sizes could be employed to operatively couple the loading head 104 and the elongate loading frame 102 together.
    [066] Referring to Figures 19 and 20, particular embodiments of the present technology provide the lower inner faces of each of the opposing sides 106 and 108 of the elongate load frame 102 with the load frame deflection faces 162 positioned to face at a slightly downward angle toward an intermediate portion of the loading frame 102. In this manner, the loading frame deflection faces 162 loosely engage the loaded coal and direct the coal downward and toward the sides of the load. coal bed that is loaded. The angle of the deflection faces 162 further compress the coal downward in a manner that helps to increase the density of the edge portions of the coal bed. In another embodiment, the front end portions of each of the opposite sides 106 and 108 of the elongate load frame 102 include load frame deflection faces 163 that are also positioned rearwardly from the wings, but are oriented to face facing forward and down from the loading frame. In this way, the deflection faces 163 can further help to increase the density of the coal bed and direct the coal outward toward the edge portions of the coal bed in an effort to more completely level the coal bed.
    [067] Many prior art coal loading systems provide a lower compaction volume on the coal bed surface due to the weight of the loading head and loading frame. However, compaction is typically limited to thirty centimeters (twelve inches) below the surface of the coal bed. Data during coal bed testing demonstrated that the bulk density measurement in this region is a three to ten point difference within the coal bed. Figure 6 graphically presents density measurements taken during simulated oven testing. The top line shows the surface density of the coal bed. The bottom two lines reveal the density at thirty centimeters (twelve inches) and sixty-one centimeters (twenty four inches) below the coal bed surface, respectively. From the testing data, it can be concluded that the bed density drops most significantly on the coke side of the furnace.
    [068] Referring to Figures 21 to 29, various embodiments of the present technology position one or more extrusion plates 166 operatively coupled to the rear face 126 of the loading head 104. In some embodiments, the extrusion plate 166 includes a face 168 which is oriented to face backwards and downwards with respect to the loading head 104. In this manner, loose coal which is loaded into the furnace behind the loading head 104 will engage the coal engagement face 168 of the extrusion plate 166. Due to the pressure of the coal that is deposited behind the loading head 104, the coal engagement face 168 compacts the coal downwards, increasing the coal density of the coal bed below the extrusion plate 166. In In various embodiments, the extrusion plate 166 extends substantially along a length of the loading head 104 in order to maximize density across a significant width of the coal bed. With continued reference to Figures 21 and 22, the extrusion plate 166 additionally includes an upper deflection face 170 which is oriented to face rearwardly and upward with respect to the loading head 104. In this manner, the carbon engagement face 168 and the upper deflection face 170 are coupled together to define a peak shape, which has a peak ridge that faces rearwardly in the opposite direction of the loading head 104. Consequently, any coal that falls on top of the deflection face upper deflection 170 will be directed away from the extrusion plate 166 to join the incoming coal before it is extruded.
    [069] In use, the coal is mixed to the front end portion of the coal loading system 100, behind the loading head 104. The coal is stacked in the opening between the conductor and the loading head 104 and the pressure of conductor current begins to build up gradually until it reaches approximately 17 MPa to 19 MPa (2500 to 2800 psi). Referring to Figure 23, coal is fed into the system behind loading head 104 and loading head 104 is retracted rearwardly through the kiln. The extrusion plate 166 compacts the coal and extrudes it into the coal bed.
    [070] Referring to Figures 24A to 25B, embodiments of the present technology may associate extrusion plates with one or more wings that extend from the loading head. Figures 24A and 24B show an embodiment in which extrusion plates 266 extend rearwardly from opposing wings 128 and 130. In such embodiments, extrusion plates 266 are provided with carbon engagement faces 268 and deflection faces. top 270 which are coupled together to define a peak shape, which has a peak ridge that faces rearward in the opposite direction to the opposing wings 128 and 130. The carbon engagement faces 268 are positioned to compact the carbon downwards. as the coal loading system is retracted through the furnace, the coal density of the coal bed below the extrusion plates 266 increases. Figures 25A and 25B show a loading head similar to that shown in Figures 12A through 12C, except for the the fact that the extrusion plates 466, which have carbon engagement faces 468 and top deflection faces 470, are positioned to extend rearwardly from opposing wings 428 and 430. The extrusion plates 46 6 function similarly to extrusion plates 266. Additional extrusion plates 466 can be positioned to extend forward from opposing wings 444 and 446, which are positioned behind loading head 400. Such extrusion plates compact the coal downwards as the coal loading system is advanced through the kiln, further increasing the coal density of the coal bed below the 466 extrusion plates.
    [071]Figure 26 shows the effect on density of a coal charge with the benefit of extrusion plate 166 (left side of coal bed) and without benefit of extrusion plate 166 (right side of coal bed). As shown, use of extrusion plate 166 provides increased coal bed bulk density area "D" and minus coal bed bulk density area "d" where extrusion plate is not present. In this way, the extrusion plate 166 not only demonstrates an improvement in surface density, but also improves the bulk density of the inner bed as a whole. The test results, shown in Figures 27 and 28 below, show the improvement in bed density with the use of the extrusion plate 166 (Figure 28) and without the use of the extrusion plate 166 (Figure 27). The data demonstrate a significant impact on both surface density and sixty-one centimeters (twenty-four inches) below the surface of the coal bed. In some testing, an extrusion plate 166 has a peak of twenty-five centimeters (ten inches) (distance behind the loading head 104 to the peak ridge of the extrusion plate 166, where the carbon engagement face 168 and the upper deflection face 170 meet). In other tests, where a fifteen centimeter (six inch) peak was used, the coal density was increased, but not to the levels that result from using the twenty-five centimeter (ten inch) peak 166 extrusion plate. The data reveal that the use of the twenty-five centimeter (ten inches) peak extrusion plate increased the density of the coal bed, which allowed for an increase in load weight of approximately two and a half tons. In some embodiments of the present technology, it is contemplated that smaller extrusion plates, thirteen to twenty-five centimeters (five to ten inches) in peak height, for example, or larger extrusion plates, twenty-five to fifty centimeters (ten to twenty inches) in peak height, for example, could be used.
    [072] Referring to Figure 29, other embodiments of the present technology provide an extrusion plate 166 that is shaped to include opposing lateral deflection faces 172 that are oriented to face rearwardly and laterally with respect to the loading head 104. conforming the extrusion plate 166 to include the opposing side deflection faces 172, testing showed that the most extruded coal flowed towards both sides of the bed as it was extruded. In this way, the extrusion plate 166 helps to promote the flat coal bed, shown in Figure 2B, as well as an increase in coal bed density across the width of the coal bed.
    [073] When loading systems extend into furnaces during loading operations, coal loading systems, typically weighing approximately 36 tons (80,000 pounds), deflect downward at their free distal ends. This deflection shortens the coal carrying capacity. Figure 5 shows that the bed height drop, due to the deflection of the coal loading system, is from thirteen centimeters to twenty centimeters (five inches to eight inches) between the pusher side and the coke side, depending on the weight of charge. In general, coal loading system deflection can cause a loss of coal volume of approximately 1 to 2 tons. During a loading operation, coal is piled up in the opening between the conductor and the loading head 104 and conductor current pressure begins to build up. Traditional coal loading systems operate at a current pressure of approximately 16 MPa (2,300 psi). However, the coal loading system of the present technology can be operated with a current pressure of approximately 17 to 19 MPa (2500 to 2800 psi). This increase in current pressure increases the stiffness of the coal loading system 100 over a length of its loading frame 102. Testing indicates that the operation of the coal loading system 100 at a current pressure of approximately 18 MPa (2,700 psi) reduces the deflection of the coal loading system by approximately five centimeters (two inches), which equals a higher load weight and increased production. Testing has further shown that operating the coal loading system 100 at a higher current pressure of approximately 21 to 23 MPa (3,000 to 3,300 psi) can produce a more effective change and additionally realize greater benefit from using one or more more extrusion plates 166 as described above.
