Abstract

The present invention relates to providing a thermal radiation and conduction shield suitable for mounting on the rear side of a protective face block placed on an opening, such as a manhole, in the refractory ceramic lining of a boiler, furnace, or like apparatus. The shield is employed in said opening in order to prevent conduction of heat through the protective face block from the firebox to those frame constructions of the apparatus that are not manufactured from heat-resistant materials. Since the material of the protective face block is typically a refractory, high-density ceramic material of very high thermal conductivity, the operating temperature of the hot side of the shield is practically equal to that of the firebox. Consequently, the backing insulation of the shield must provide effective thermal insulation as well as good resistance to high temperatures. A third prerequisite is resistance to mechanical stress under practical operating conditions.
