ABSTRACT:
A coke oven charging hole that dissipates heat emanating from the oven so that the cover resists warping due to overheating. The concentration of large amounts of heat directly above the charging hole is also avoided. A lower concave housing member fits into the charging hole and is partially filled with insulation. A circular plate is fixed to this housing member so as to form an insulating air space between this plate and the insulation. One or more other plates are superimposed over this plate so as to form heat air spaces which are open to ambient air so that a laterally directed flow of air is established in these air spaces.
