Abstract: Proposed is a pyrolysis reactor for processing solid municipal and domestic wastes by means of a pyrolytic reaction in the pyrolysis chamber without access of oxygen to the reaction system. The reactor is characterized by containing two waste-feeding screws which have tapered shapes, a gap between the outer surfaces of the threads, are inclined in the vertical plane and converge towards each other in a horizontal plane in the direction from the inlet to the outlet end. The gap is adjustable with diminishing toward the outlet end.

Abstract: A method and apparatus for quenching metallurgical coke made in a coking oven. The method includes pushing a unitary slab of incandescent coke onto a substantially planar receiving surface of an enclosed quenching car so that substantially all of the coke from the coking oven is pushed as a unitary slab onto the receiving surface of the quenching car. The slab of incandescent coke is quenched in an enclosed environment within the quenching car with a plurality of water quench nozzles while submerging at least a portion of the slab of incandescent coke by raising a water level in the quenching car. Subsequent to quenching the coke, the planar receiving surface is tilted to an angle sufficient to slide the quenched coke off of the planar receiving surface and onto a product collection conveyer and sufficient to drain water from the quenched coke.

Abstract: A rotary drum cooler having a shell for cooling particulate material (e.g. coke particles) wherein the volumetric capacity of the lifters within the shell which lift the material from the bottom of the shell to the exit thereof can be adjusted to thereby affect the exit parameters (e.g. temperature, particle size, etc.) of the cooled particulate material.

Abstract: The present invention deals with a method to produce uniform quality coke for a blast furnace by quenching coke at a pre-determined rate to produce coke with essentially uniform moisture; further, this invention possesses specific features to produce coke of uniform stability (strength) by equilibrating the temperature of the coke prior to its being quenched. Uniform moisture and uniform stability are very important factors that contribute to the efficient operation of the blast furnace to result in lowering the cost of making a ton of iron. This method is carried out under pressure, in a closed system, and in an environmentally acceptable manner with minimum formation of CO.sub.2. Further, the method possesses additional features which lead to the production of coke of higher stability than obtained conventionally.

Abstract: A system that reduces worker exposure during coke drum unheading and cutting operations and that reduces risk to workers also provides a capacity increase in that the time a coke drum is not being filled is reduced. This system employs a containment shield that safely permits drainage through the bottom head and contains water and coke avalanches.

Abstract: A rotary coke cooling drum is formed of plural opposed folded plates welded together and having spaced apart openings for receiving an array of tubular cooling pockets which are separately formed and are insertable in the openings to provide heat transfer surfaces and auger flights for traversing material through the drum. The cooling pockets are formed by opposed trapezoidal shaped plate members which are welded to each other along mating edges leaving one end of the cooling pocket substantially open and the opposite end is closed over a major portion by an end cap and a short section of drain conduit adapted to project through the wall of the drum shell. The cooling pockets may each have a locating and mounting flange or doubler plate secured at the open end of the pockets and adapted to be welded to the wall of the drum shell. The pockets are easily inserted in and removed from the drum shell for repair or replacement as needed.

Abstract: A method and apparatus for quenching a gas stream in the production of vinyl chloride monomer includes the use of a knock back condenser and a plurality of column fractional distillation trays disposed within the quench column, and a liquid stream of 1,2-dichloroethane, vinyl chloride, and hydrogen chloride may be removed from the bottom column fractional distillation tray.

Abstract: A twin wall coke quenching container having an upwardly slanting bottom, there being a first plurality of quenching water inlets in an upper portion of that bottom, the openings of the first plurality having axes transverse to the upwardly slanting bottom; a second plurality of water inlet openings are disposed in front and rear walls not much higher than a level of that edge and being arranged only in the bottom portion having the first plurality of openings; a third plurality of water inlet openings extend along the upper edge, and axial inclination similar to said slant of the bottom.

Abstract: A bulk hot coke cooler with a vessel for holding the coolant material and a drum rotatably supported within the vessel so that when the drum rotates, it moves through the coolant, the drum having a plurality of hollow cooling pockets going from one side of the drum to the other which directly contact the hot coke in the drum through which pockets coolant can flow as the drum rotates to enhance the cooling effect of the coolant on the hot coke inside the drum, wear sleeves provided on the edges of selected pockets to protect the lead surfaces of the pockets which come in contact with the hot coke, the wear sleeves being shaped to match the shape of the pocket surface where they are attached, and transfer bars connected to the wear sleeves which move and push the coke through the drum. The various parts of the cooler can be fabricated from hardfaced plate.

Abstract: A coke car is moved along a battery of coke ovens to a location for receiving coke from an oven chamber while the car is stationary and for moving to beneath a quenching tower. The coke car includes a generally square box-like container having side walls sealed with a floor that is pivoted about a horizontal axis to bear against seal members. The horizontal axis is spaced from the wall of the car adjacent the coke bench by a distance less than the distance between the axis and the wall of the car adjacent the oven platform. The seal members are disposed on the top of part of the floor which moves away from a side wall during pivotal movement and seal members are disposed on the bottom of a floor part which moves upwardly along a wall of the container during pivotal movement.

Abstract: A furnace for thermal processing of lump solid fuel, comprising a body accommodating a semicoking zone, zones for gasifying semicoke and for cooling waste solid material and chambers adapted for feeding gas into said zones and discharging a vapor-gas mixture therefrom, said zones and chambers being arranged in succession along the height of the furnace body. The furnace is furnished with an unloading device for discharging solid waste material, said device being located in the bottom part of the furnace body and constituting a hopper with a water seal having a cylindrical bottom passing into a sloping trough. Mounted above the cylindrical portion of the bottom is a sector rocking-type pusher and above the sloping trough - a mechanical shovel associated with the sector pusher in such a manner that a working stroke of the sector pusher corresponds to an idle stroke of the mechanical shovel.

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.
