    1525442 Preheating charges for coke ovens HUTNI PROJEKT PRAHA 19 Jan 1977 [21 Jan 1976] 02027/77 Heading F4B Particulate coal to be fed to a coke oven is preheated in a shaft 8 with gases from a combustion chamber 7, and the coal and exhaust gases are fed to one or other of two separator sets, each comprising a primary cyclone 11, 41, and at least one secondary cyclone 15, 45, the outlets from the cyclones of each set being fed through a valve 12, 42 to a bin 13, 43 having a metered outlet to the coke oven, and the gases from each set of secondary cyclones are fed partly to a heat exchanger 20 to cool the gases and may fire coal emitted to atmosphere, and partly through a fan 18 to the combustion chamber 7 of the preheater. The heat exchanger 20 may provide heated air for the combustion chamber 7, and gases leaving the heat exchanger may be filtered at 22, the fire coal removed in filter 22 being collected for use elsewhere or fed to the burner 32 of the combustion chamber 7.

    (54) INSTALLATION FOR COOLING THERMAL PREPARATION FOR COXING
    through which cooling of residual, dry and fine coal dust is achieved, a filter 21 with a shutter 22, an accumulator 23, a shutter 24, a dosing accumulator 25 for coal coal are installed, and a dispenser 26 for dispensing this dust into the burner 27 installed in the combustion chamber 3.
    A wet coked mixture from a coal bunker or a special storage tank 28 is fed by means of a conveyor belt 29 through stretch tape or device 30 to a feeder 31. Feeder 31 has a control device 32 of the minimum and maximum content of the wet mixture. The coked mixture is pumped by means 2 for feeding while continuously adjusting the loading dose directly to dryer 1. In dryer 1, the wet coxuem mixture is first dried and then heated to an appropriate temperature in the range of 180-280 ° C and supplied together with a heated medium to distributor 4. Distributor 4 manages the preheated coking mixture with the preheated medium in pipelines 33 and 34. Through the conduit 33 or 34, the coxuem preheated mixture and the preheated medium are supplied to the primary cyclone 5 or 6, where approximately flax 90% of the heated coking mixture. Through the shutter 7 or 8 of the coxuem, the mixture enters the hopper 9 or 10, depending on what system of cyclones is in operation. The heated medium with a residual of about 10% of the heated coking medium enters secondary cyclones 11 or 12, which are predominantly on top of primary cyclones 5 or 6. In secondary cyclones I or 12, 9% of the heated coking mixture is released, which is iodized by gravity into the lower part of the primary cyclone 5 or 6 and then goes along with the heated coking mixture from the primary cyclone 5 or 6 through the bolt 7 or 8 into the hopper 9 or 10. If the hopper 9 or 10 contains the amount of heated load that is sufficient for filling no coke chamber, the valve 4 directs the heated medium to the preheated coking mixture from the dryer 1 to the second cyclone system which is currently inactive. In the second system, the separation cycle is repeated. In this case, one of the two bins 9 or 10 is ready for unloading into the coke oven chamber,. the second is ready to accept the separated Coked mixture.
    The cycle of filling and unloading the hoppers 9 and 10 is alternately repeated.
    The heated medium flows out of the secondary cyclones 11 or 12 into the pipelines 13 or 14, which flow into the common pipeline 15, alternately in accordance with the filling cycle of the hoppers 9 "10. The heated medium is divided in the pipeline 15 into two streams from which.
    one through the suction pipe 16, the pneumatic installation 17 and the pressure pipe 18 are supplied to the combustion chamber 3 to supplement and cool the combustion materials and to accumulate the required amount of heat carrier.
    The second part of this medium — the residue enters — through conduit 19 to the heat exchanger 20, where it is cooled above the point
    10 dew water vapor. From heat exchanger 20, the remainder of the medium is directed through conduit 35 to the drying filter 21, in which this medium loses about one percent of the smallest coal particles and is removed from the dust into the atmosphere through channel 36.
    The coal dust captured in the filter 21 is directed through the shutter 22 to the accumulator 23. The fine coal dust can then be sent under its own weight through the shutter 24 to the container 37, from where it can be used outside the coking plant for processing. However, from a control point of view, it is preferable and more reliable to direct the coal dust from the accumulator 23 with the shutter 22 closed and the shutter 24 respectively installed into the accumulator 25.
    From the accumulator 25, coal dust through the dispenser 26 is transported through pipe 38 to burner 27 and is used in the combustion chamber 3 as an additional medium, the coolant.
    Combustible gas, usually coke oven gas, or 5 coke oven gas mixed with top gas is supplied through conduit 39 to burner 27. Air required for combustion is sucked through conduit 40, directed through heat exchanger 20 and, with significant heating, is sucked through conduit 41 to pneumatic installation
    42 and further down the line.
    43k burners 27.
    The installation is equipped with automatic
    5 adjustment devices and other safety devices that provide automatic control, eliminating the likelihood of an explosion. The advantage of such an installation is that instead of the currently known collective storage tank for preheated coal and the distributors and conveyors directed from it to the dosing tank, they are called
    5 two alternately operating branched systems of primary and secondary centrifugal dust separators.
    Another advantage is that the coke-chew mixture with the heated medium

    0 is sent to cyclones and further under the action of its own weight falls directly into the bunker. Due to this, there is no longer any transportation of the coked mixture through screw conveyors, rack conveyors, chamber conveyors - 5 conveyors and the like. By eliminating mechanical transorters, simplification of supply and elimination of various sources of interference and depressurization, which often lead to pollution of the atmosphere with coal dust and toxic gases, and is achieved. All this. Leads to increased reliability. An apparatus for heat treatment of coal to coking, comprising a dryer installed in series with means 7 for supplying coal and heating and a cyclone system with a hopper, characterized in that, in order to increase reliability in operation and ensure uniform supply of coal to the coke oven by preventing sticking together heat-treated coal, it is equipped with an additional cyclone system with a bunker connected to the first cyclone system in parallel, and the silos are located under the cyclones.
