Abstract:
1. A coke oven comprising: 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; at least one oven door closing the door opening; and a peripheral gas channel extending around the opening between the door and coke-oven chamber and having at least one outer and at least one inner door seal defining an annular space, the inner door seal being formed in both the coke-oven chamber and the gas-collecting chamber with 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 so that 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.
