Abstract

A coke oven door, which includes a metal frame, means for latching the door in a closed position, a sealing member extending around the perimeter of the frame having forward edges adapted to contact a sealing surface on a coking chamber door jamb for effecting a continuous seal. The coke oven battery also having at least one attached protrusion proximate the coking chamber extending outwardly from the battery, such as a latch or a guide bar, said door comprising a door plug passing with clearance and fitting into the coke oven, said plug having an inner surface that forms an interior end wall of the coke oven wherein a first plane is formed by the perimeter of said inner surface. Said door further having a first horizontal dimension between said forward edge of said sealing member and said first plane, and said coke oven battery having a second horizontal dimension between the sealing surface on the door jamb and a second plane that is parallel to a plane formed by said sealing surface of the door jamb which includes the furthest point on the protrusion from the sealing surface on the door jamb, wherein the first dimension is greater than the second dimension, so that when the coke oven door is being placed on the coke oven and is improperly aligned, said door plug comes into contact with the coke oven door jamb to stop further movement of the door and prevent the sealing member from coming into contact with the protrusion.
