APPARATUS FOR PREVENTING GAS LEAKAGE FROM OVEN DOOR OF COKE OVEN ABSTRACT OF THE DISCLOSURE In a coke oven of the type comprising an oven opening, an oven door for closing the oven opening, a knife-edge surrounding the oven door for forming a seal for preventing leakage of oven gas, the improvement comprises a conduit arranged along the outside periphery of the oven opening and provided with a plurality gas ejection nozzles and means for supplying compressed gas to the conduit, and the gas ejection nozzles are directed such that gas is blasted to the seal. The blasted gas effectively cools the knife-edge, the door and the door frame thereby reducing the thermal distortions thereof and promotes adhesion of tar and/or pitch thereby increasing the sealing effect.
