ABSTRACT:
A sealing closure for an opening of a coking oven includes a frame mounted on the coking oven about the opening, a door receivable in the frame with a clearance therefrom in a closing position, and an arrangement for sealing the clearance. The sealing arrangement consists of a sealing member including a rigid support element and a sealing element of a resiliently yieldable material mounted on a marginal portion of the support element and adapted to sealingly contact a contact surface of the frame in the closing position of the door. The support element is connected to the door for an adjustment of the position thereof, and is retained in a selected adjusted position. A marginal portion of the support element is received in an elongated recess and has longitudinally distributed projections which are accommodated in a plurality of cutouts in the sealing element, the cutouts extending from the recess to a sealing surface contacting the contact surface of the frame. The projections have dovetail shapes and project from the remainder of the support element to a distance which is smaller than the corresponding dimension of the respective cutout. The frame may include an inner frame member, and an outer frame member provided with the contact surface and mounted on the inner frame member, being separated therefrom by a heat insulation. The outer frame member may have a width corresponding to that of the contact surface, and a thickness which is substantially smaller than that of the inner frame member. The inner frame member may have a stepped ridge between the opening and the outer frame member, and the door may be configurated complementarily to the ridge. At least one groove may be provided on the frame, and the door may have a projecting bulge extending into the groove in the closing projection of the door to define a labyrinthine passage therewith. A resilient sheet member may be removably interposed between the door and the frame.
