Abstract: A coke oven door includes a mainframe, a diaphragm assembly coupled with the mainframe, and a plurality of load-exerting assemblies attached to the mainframe. The diaphragm assembly includes a pan and a sealing edge structure attached to the pan. The sealing edge structure includes a load-receiving surface, a door-sealing surface spaced from the load-receiving surface, and a plurality of scallops spaced from one another. Each of the load-exerting assemblies is positioned and configured to selectively, operably apply a load to the load-receiving surface of the sealing edge structure. The scallops are configured and positioned to facilitate deflection of the sealing edge structure, in response to loads applied to the load-receiving surface, such that the door-sealing surface is configured to be positioned in contacting, and at least substantially sealing, engagement with a door jamb of a coke oven body.
