Abstract: A coke oven door for closing the open end of an elongated coking chamber of a nonrecovery coke oven, including process air vents extending through the door at a level above a coal charge to be coked, has a structural frame on its outer surface including an elongated manifold extending across the door adjacent its bottom with a plurality of inlet openings in the manifold, and a tubular duct system connecting the manifold to the process air inlets whereby reduced pressure in the oven will draw air through the process air inlets and the duct system to thereby draw emissions from the area at the base of the door into the oven for incineration.
