Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
125 words
A fuel burning apparatus comprising a burner assembly; a conical air baffle having an open apex and including means to produce a vortical flow of air, said burner assembly projecting upwardly through the open apex of said air baffle, said burner assembly comprising a burner head adapted for connection to a source of fuel, said burner head having a plurality of radially extending horizontal passages for discharge of fuel within said conical air baffle and a circular flame spreader plate disposed above said burner head adjacent said open apex and located in a plane parallel to the plane of the burner head passages, fuel discharge from the passages in said burner head being dispersed and deflected thereby to produce a substantially continuous ring of flame.
Claim 2
Dependent Claim
125 words
A fuel burning apparatus comprising a burner assembly; a conical air baffle having an open apex and including means to produce a vortical flow of air, said burner assembly projecting upwardly through the open apex of said air baffle, said burner assembly comprising a burner head adapted for connection to a source of fuel, said burner head having a plurality of radially extending horizontal passages for discharge of fuel within said conical air baffle and a circular flame spreader plate disposed above said burner head adjacent said open apex and located in a plane parallel to the plane of the burner head passages, fuel discharge from the passages in said burner head being dispersed and deflected thereby to produce a substantially continuous ring of flame.
Claim 3
Dependent Claim
57 words
A fuel burning apparatus according to claim 1 wherein said air baffle means has an inverted conical shape with vortex inducing louvers formed therein for passage of air therethrough, the vortical flow of air past said burner assembly minimizing impingement of the flame on said baffle and causing intimate mixing of fuel and air for efficient combustion.
