ABSTRACT:
A vented coke oven door includes a door frame having a vertical face surface carrying a plug assembly having a central vertical internal opening to conduct coke oven gas generated at the bottom of a coal charge in a coke oven chamber. The plug assembly includes a plurality of U-shaped refractory plug segments arranged in an end-to-end aligned relation with leg sections of each U-shaped segment extending horizontally into an abutting relation with the face surface of the door frame. Each leg section carries either an embedded hooked end or a T-shaped head of a threaded fastener which is supported by the door frame so that the leg sections are unrestrained against movement toward and away from each other in response to a thermal gradient across the wall thickness of the refractory plug segment. A backing plug plate is fitted into a recess in the leg sections of each plug segment to provide a closure wall to the U-shaped configuration of the segments and forms the vertical passageway for conducting coke oven gas. The backing plug plate has an exposed layer of cast refractory overlying a layer of insulation used to protect the door frame. A seal strip extends about the outer periphery of the door frame to prevent emission of coke oven gas from the coking chamber.
