Abstract: A coke oven emission control system comprising a traveling hood for the quench car into which hot coke is pushed from the coke oven. The hood is independently supported by wheels traveling on rails and is of a length to cover the entire length of the quench car. The hood is moved by the movement of the quench car to and from a quench station, through beams at opposite ends of the quench car that are selectively raised and lowered into and out of a position for engagement with the hood. The top of the hood is provided with a central elongate hollow neck which projects upwardly into a longitudinally slotted exhaust duct paralleling the battery of ovens. The slot in the duct has a pair of parallel extending flexible sealing strips which are biased toward sealing engagement with each other across the slot and which separate to seal on the neck of the hood as it slides longitudinally along the duct. Selective communication is thus provided for flow of fumes, gas, smoke, particulates, etc.

Abstract: An improved method of rapid liquid quenching of coke wherein hot coke is distributed on a surface, preferably an inclined surface, and a substantially uniform stream of quench liquid is flowed through said hot coke at spaced apart locations so that the quench liquid penetrates the depth of the bed prior to complete vaporization and percolates through the bed quenching coke as it goes. Particularly good results are obtained by oscillating the stream or streams slowly over the coke.

Abstract: A method and apparatus for the production of coke from coal by a dry distillation operation wherein the coking plant is provided with a computer unit that receives signals from the coal leveling mechanism, the door mechanism, the quenching car mechanism, and a signal value for the time required to achieve the coking of the coal. The computer prevents the opening of any given coking chamber until the minimum coking time has lapsed and the opening of the chamber and discharging and quenching of the coke is correlated to the actual operating conditions rushing at that time. If desired, the charging and emptying operations may be carried out on a completely automatic basis.

Abstract: The quenching apparatus includes a collector or receiver positioned above and connected to a quenching vessel. Incandescent coke pushed from a coke oven is deposited in the receiver and fed at a controlled rate from the receiver into the upper portion of the quenching vessel. Nozzles positioned adjacent the top of the quenching vessel spray quenching water on the incandescent coke as it is introduced into the quenching vessel. A suction device is provided adjacent the lower portion of the quenching vessel to draw the vaporized quenching water downwardly through the bed of quenched coke in the quenching vessel and discharge the quenching vapors to the atmosphere. The bed of quenched coke serves as a filter to remove the particulate material from the quenched water vapor.

Abstract: A coke quencher car apparatus comprises a receptacle that is similar to a standard quencher car, but having one internal baffle forming coke compartments, and a frame at each end thereof on which is supported metal curtain material. Each curtain is stretchable to cover one of the coke compartments during and after the pushing of coke is completed. The quencher car is connected to a traction car carrying equipment to remove and clean gases arising from the pushed coke in the quencher car and to move the quenching car.

Abstract: An improved method and apparatus for by-product coke oven operation wherein the problems of pollution caused by charging, oxidation of the coke during pushing, transportation of the incandescent coke to a quenching tower and quenching of the coke is eliminated by the evacuation of the gases during charging, by quenching the coke in a closed system during the push so that the temperature of the coke leaving the guide is below its ignition point; the combustion gases created by the charging and the steam and gases generated by the quenching are extracted and cleaned in a centralized dust collection system. The coke being quenched in a sealed system to a temperature lower than its ignition point, eliminates the oxidation thereof and the efficiency of the oven is increased by being able to push in shorter schedules as the necessity for extra coking time now taken to insure that all the green coke is coked, is obviated.

The tank is made up of a plurality of heat resistant metal plates which are suspended in loosely adjacent layers from strips and they overlap their adjacent plates. The tank includes a bottom with openable door means for selectively opening and closing a bottom discharge for discharging the coke into a receiving bunker. A separator and washer is connected to the tank for withdrawing gaseous dust and odors and for subjecting them to a washing and a removal of the dust. The tank carries a sealing sleeve which is engageable between the exterior of the tank around the bottom discharge and a bunker to seal the space therebetween during the discharge.

Abstract: In the present method the bulk material, especially coke, is maintained at a substantially constant level on a substantially horizontal support surface. The quenching liquid is permitted to flow uniformly through the bulk material for about 45 to 90 seconds until the vapor temperature is cooled down to at least 400.degree.C. The quantity of the quenching liquid which is uniformly distributed over the bulk material is selected so that it evaporates substantially completely, except for a small moisture content in the quenched material. The present bulk material quenching apparatus has a fireproof container resting on a supporting box, the top of which is a grid structure which simultaneously forms a permeable bottom for the quenching container which is provided with a tightly closing cover. A pipe conduit is connected to the cover which has a plurality of conduit outlet openings directed into the container. The box on which the container rests has at least one hinged side wall.

Abstract: Upon discharge from a coke oven, highly heated coke is cooled by charging the hot coke to a shaft cooler wherein it is contacted with an inert cooling gas to a temperature of between 600.degree.-800.degree.F, the coke then being discharged through a pressure retention device and to a quench bunker by means of a feeding device, with the coke further cooled to a temperature of below 300.degree.F by water sprays, while preventing entrance of steam into the shaft cooler. The feed means and quench bunker are enclosed so as to prevent discharge to the atmosphere of steam produced on contact of the spray with the coke as well as particulate material carried thereby. The coke at below 300.degree.F is then fed to a conveyor for removal from the cooling area.

Abstract: A shed encloses a coke wharf onto which hot coke is pushed, the coke cake passing through a coke guide into the shed. Doors in the shed are disposed opposite the coke oven chambers and each door is openable when a coke guide is positioned at an oven to be pushed. Deflector means are located inside the shed at each door that break up and spread the coke onto the coke wharf. Fumes that evolve from the coke on the wharf as it is being quenched are collected in a main. An auxiliary collecting main and hood structure are located above the coke oven doors, whereby effluent arising from coke in the chambers after the oven doors are removed are collected in the auxiliary collecting main and conducted thence into the collecting main.
