ABSTRACT:
A coke oven has a coke-oven chamber adapted to hold a mass of coke, defining above the mass of coke a gas-collecting chamber, and having a door opening. A door closes the door opening. A peripheral gas channel extends around the opening between the door and coke-oven chamber and has at least one outer and at least one inner door seal defining an annular space. The inner door seal is formed in both the coke-oven chamber and the gas-collecting chamber with a plurality of throughgoing holes forming fluid-communicating connections between the coke-oven chamber, the gas-collecting chamber, and the annular space at different heights of the coke-oven chamber and of the gas-collecting chamber. Thus regions of the coke-oven chamber with different gas pressures communicate with each other and with the annular space via the connections on the inner door seal to equalize pressure between the regions and the gas-collecting chamber.
