Abstract: The invention relates to a coke oven door with a sealing element which consists of a metal sealing strip and a crowned metal diaphragm. When the sealing strip is pressed onto the door frame a wedge-shaped gap is produced between the sealing strip and the door frame into which the tarry condensation residues pass as a result of the movement of the sealing strip and ensure a good seal.

Abstract: A self-sealing door assembly for a coke oven comprises a door frame affixed around the oven opening, the surfaces of the frame facing the oven defining a gap which is filled with heat insulating material, and the outer front surfaces of the frame cooperating with iron sealing strips on the body of the door. The gap filled with insulating material is defined between the vertical and transverse surfaces on the door frame facing the oven and an internal angle-sectioned cover divided around the periphery of the door frame into a plurality of overlapping sections which are supported on distance pieces attached to the surfaces of the door frame.

Abstract: Apparatus for servicing coke ovens has a framework movable along the coke oven battery. A horizontally rotatable and vertically pivotable boom has one end mounted on the gantry and a coke oven work tool on the other. The framework includes a coke quenching apparatus and conveying equipment.
