Abstract
A leveler door for sealing the leveler opening in a coke oven door; the oven door of the type having leveler door mounting and latching apparatus associated therewith. The leveler door comprising a flexible closure member possessing spring-like properties at elevated temperatures and having a generally concave shape, terminating in a flexible sealing edge at its outer periphery. The sealing edge is formed at an angle of less than 90.degree. relative to the plane of the leveler opening. Means for securing the closure member to the mounting and latching apparatus of the coke oven door are disclosed, whereby the compressive closing force supplied by the mounting and latching apparatus causes the concave closure member to move toward the leveler opening causing the sealing edge to concurrently flex outwardly from the leveler opening while sealably engaging the coke oven door adjacent the leveler opening. Also disclosed is a detachable sealing seat adapted for placement around the leveler opening providing improved sealability in combination with the flexible sealing edge of the closure member.
