Abstract
Abstract A burner assembly producing radiant heat by discharging the burning fuel towards the surface of a refractory structure from which the heat radiates onto objects or articles to be heated. The face of the ceramic structure is provided with fissures into which the burning fuel enters and recycles to increase the temperature of the refractory structure from which heat radiates.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
135 words
A burner assembly for producing radiant heat comprising, a furnace wall formed of ceramic material, said wall having an inner face arranged in one general plane, a burner head projecting through said wall having slots therein for the escape of a fuel mixture in directions radially of the burner head and towards said inner face whereby the burning fuel and the hot products of combustion move over the inner face of said wall radially outwardly from said burner head, said wall having grooves therein open at said inner face, and side surfaces of said grooves being disposed generally transversely of lines which project along said inner face and radially from said burner head whereby some of the hot gases and flame enter the grooves and cycle therein to heat the ceramic wall within the grooves.
