ABSTRACT:
A closure for an opening of a coking oven includes a door receivable in an opening of a circumferentially complete frame mounted on the coking oven, with a clearance therefrom. The clearance is sealed by a sealing member adjustably mounted on the door and contacting a contact surface of the frame in the closing position of the door. The contact surface of the frame and the sealing member are protected from deposition of volatile byproducts of the coking process thereon by an outwardly projecting circumferentially complete stepped ridge provided on the frame in between the open end of the opening and the contact surface of the frame. At least one groove may circumferentially surround the open end of the opening, and the door may have regions juxtaposable with the steps of the ridge and with the groove and having configurations complementary to the ridge and the groove to define a labyrinthine passage for the volatile byproducts between the open end and the contact surface of the frame. A generally U-shaped sheet member of resilient properties may be interposed between and bear against the door and the frame.
