ABSTRACT OF THE DISCLOSURE A coke oven door construction, adaptable for either the pusher side or the coke side of the oven, has a diaphragm arranged so as to exert an even pressure all around the door and associated jamb when the door is locked in the jamb by a suitable locking device. After the door has been locked in place, air is connected to the bottom of the door so as to permit injection of a mixture of air and a suitable anti-stick agent all around the door diaphragm and onto the sealing surface of the associated jamb. The anti-stick agent keeps carbon and other foreign matter from sticking to the diaphragm and jamb surfaces. Further, if a fire occurs between the sealing surfaces, it can be extinguished by connecting the air to the doors. The air mixed with the anti-stick agent is preferably preheated before it reaches the jamb surface so as to prevent warping of the jambs. In addition, to eliminate vertical warping of the door,the frame fo the door is made flexible in the middle thereof, and the flexible portion of the frame is spirng loaded so as to hold the frame straight until the jamb moves inboard or outboard of the frame. If the jamb does move, the door seal will move with it keeping the same pressure on the seal at all times.
