Abstract

See full text

Combustion apparatus for use with a solid fuel has a firebox constructed at least in part of a fired refractory carbide material. The fired refractory carbide material has a catalytic effect on the combustion process providing a cleaner and more efficient combustion. The fired refractory material also absorbs heat from the combustion process directly or indirectly by heat exchange with combustion products and dissipates the absorbed heat over an extended period of time providing space heating after the combustion process is completed.
