Abstract
Abstract A flexible seal member is secured to the periphery of the body of a coke oven door that is shaped to the contour of the receiving door jamb of the coke oven body. A seal edge of the seal member contacts the jamb in sealing relation. A plurality of spring pressing elements secured to the periphery of the door exert a constant sealing pressure on the seal member to maintain the seal member in sealing relation with the jamb. A plurality of stop mechanisms arranged on the periphery of the door maintain a preselected distance between the fastening point of the seal member to the door and the sealing surface of the jamb. A plurality of latching mechanisms positioned at selected regions on the door and secured to the coke oven body are operable to bend the door according to the contour of the jamb as the door experiences deformation during the coking operation. The bending of the door is also enhanced by reducing the moment of resistance of the door by providing longitudinal recesses therein. Thus, the seal member is maintained in sealing relation with the jamb as the door experiences deformation during the coking operation.
