Abstract

A coke oven door for a coke oven which has an oven opening with a receiving frame extending around the opening comprises a door body with a sealing plate secured to the face of the door body which is adapted to close the oven opening. The sealing plate is of thin metal material and is held in spaced relationship to the front face of the door body by spacers. The plate includes an annular peripheral portion with an inturned flange directed inwardly toward the receiving frame. Spring biasing means mounted on the door engage against the rear edge of the flange at spaced locations around its periphery and bias the flange inwardly into sealing engagement with the receiving frame.
