Abstract
A coke oven door seal and corresponding door jamb are disclosed which provide apparatus coaction which is self-aligning and self-cleaning. The seal is pressurized, with a relatively inert atmosphere, above the range of pressures incurred within the coke oven, thus preventing escape of pollutants. A plurality of pressure maintaining devices maintain sealed contact between the door seal and the door jamb.
