ABSTRACT:
A coke oven door comprises a flat sealing diaphragm which is secured between and spaced apart from the door body and the door plug and is provided on its periphery with sealing knife edges which project against the door frame. The sealing edges are pressed against the door frame by bias adjustable springs, through spring loaded plungers. The door plug is formed by a plurality of individual plug elements closely adjacent to each other and supported by associated plug holders, and the sealing diaphragm is firmly screwed in place between the door body and the plug holders only in the upper and lower zones or areas of the door. In the intermediate zone, the diaphragm is connected to a back-up plate and to the plug holders and held adjustably spaced apart from the door body.
