A lightweight, flexible oven door for horizontal coke ovens consisting of a thin-walled, flexible sealing plate, door body, a coking plate assembly extending into the oven from the sealing plate door body, knife edges mounted on the inner periphery of the sealing plate door body and adapted to be pressed against the coke oven door frame, and a plurality of flexible pressure-balancing lever systems that cooperate with the door locking bar assemblies and locking hooks. Each of the flexible pressure-balancing lever systems applies pressure at several points along the outer periphery of the sealing plate door body to press the knife edges on the underside thereof against the door frame to seal the oven against the atmosphere. Each of the pressure balancing lever systems includes a plurality of flexibly interconnected levers.

Lightweight flexible coke oven door with pressure-balancing lever system

A lightweight self-sealing flexible door for closing the end of a horizontal coke oven, which door comprises an outer assembly that includes a thin flexible plate and an inner plate assembly that extends into the oven and is supported by the outer assembly. Self adjusting pressure-distributing means associated with the exterior of the flexible plate continuously exert pressure at a plurality of spaced locations adjacent the outer periphery of the flexible plate to cause it to freely flex and urge sealing means adjacent the inner periphery of the flexible plate to substantially sealingly engage the surface of the frame of the oven as the frame is caused to warp and distort by the thermal cycling that occurs during operation of the coke oven. Latching devices hold the door in position against the oven frame and apply pressure upon the pressure-distributing means.

Self sealing coke oven door of lightweight construction

A coke-oven door for a horizontal coking chamber has a metallic body with an inner surface covered by a thermally insulating layer and a metal plate mounted with the aid of vertically separated spacers on that inner surface. The plate consists essentially of a multiplicity of sections longitudinally adjoining or overlapping one another with limited mobility to facilitate relative thermal expansion. Each spacer comprises a first member secured to the door body and a second member coupled with an associated plate section, or with two such sections in their region of overlap, these members being interconnected with mutual play and/or with relative adjustability.

Coke-oven door

A water-aeration apparatus has a tubular frame defining a substantially closed chamber and capable of floating and carrying a load when the chamber is filled with air. Flood and bleed valves are provided at respective underwater water intakes and above-water air exhausts for introducing water into the chamber and for withdrawing air therefrom. A double-walled conduit is supported on the frame and has an outer substantially gas-impervious wall and, spaced inwardly therefrom, an inner gas-pervious wall. The conduit is inclined to the horizontal when the frame is floating and has an upper conduit end and a lower conduit end. A pump carried on the frame has an air intake above the water when the frame is floating and an air output at the lower end and directed toward the upper end.

Floating jet aerator

An exhaust hood connectable with an unloading carriage during juxtaposition thereof with a coking chamber and designed to overlie a quenching wagon alongside that carriage has walls converging upward to a roof having two ducts rising from its front and rear ends, these ducts merging into a substantially centrally positioned vertical flue with an inserted dust filter and a downward extension forming a normally closed bunker for the reception of solids dislodged from the filter by periodic vibration thereof. A bypass is formed by a branch of the flue which can be linked during unloading with a pipe atop the juxtaposed carriage having an intake end above the region of the coking-chamber door to pick up waste gases escaping there. The hood may be supported by an ancillary guide track and an overhanging shelf on the side of the quenching wagon opposite the carriage track; alternatively, it is guided at one end on lateral rails of the quenching wagon and at its other end by an outrigger riding the track of that wagon, possibly in front of an engine towing same.

Exhaust hood for unloading assembly of coke-oven battery

An apparatus for withdrawing and cleaning emissions of a battery of coke ovens, which emissions occur during the filling, coking, especially within the region of the doors, and during the pushing. The battery of coke ovens includes a charging larry with a withdrawal device for the filling gases. This battery is provided with suction conduits located on both sides of the battery and above the doors, while extending in the longitudinal direction of the battery. Connected to the suction conduits are collecting chambers for dust laden gases which rise within the region of the doors. A coke quenching car is displaceable substantially parallel to the battery. The coke quenching car has associated therewith a collecting hood which extends over the coke quenching car and which is provided with a withdrawing device for dust laden gases and vapors. Parallel and in spaced relationship to the battery of coke ovens there is provided a further withdrawing conduit having connected thereto the withdrawing device of the collecting hood associated with the quenching car. On one of the suction lines there is provided a plurality of pipe connections respectively associated with one and with one only of the oven chambers. The withdrawing device of the filling car is respectively connectable to one of the pipe sections, while both suction lines and the withdrawing conduit are connected to a common purifying device and suction blower.

Apparatus for withdrawing and cleaning emissions of a battery of coke

A device for collecting emissions rising from a quenching car of a battery of coke ovens which device is displaceable on rails parallel to the battery of coke ovens and a collecting conduit for the emissions of the quenching car. The device includes a withdrawal connection for the emissions which is connectable to desired spots of the collecting conduit. The device also includes a first hood above which there is provided a collector for the emissions which extends in the longitudinal direction of the first hood. At one end of the first hood the collector is provided with a transition or conveying member from the first hood to the collector. This transition or conveying member has associated therewith a pre-adjustable throttle flap. The other end of the collector is provided with a connecting section for a corresponding opening provided in a second hood which extends over the coke mass transporting carriage the collector is provided with a withdrawal connection having a shut-off flap for interrupting the connection between the collector and the collecting conduit.
