Process for the biological treatment of waste water using microorganisms

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.
