Abstract

Abstract There is disclosed a heat transfer device which combines controllable, infrared electromagnetic energy transfer with controllable, convective energy transfer and as desired, mass transfer of water or solvent vapors and which includes the use of a porous refractory board matrix which is secured to a single-chamber gas/air mixture plenum by means of compression fitted pins and through which the gas/air mixture passes and is combusted at and/or within the outer surface, said combustion producing both radiant heat source and hot gas heat source, and the use of incrementally attached air knife subassemblies which supply non-combustible gas flow outwardly in a controllable manner which both constricts the combustion to the surface of the matrix and reduces the temperature of the gaseous products of combustion and, as desired, permits the resultant mixed gas flow to be impinged upon target(s) to be heated or to be exhausted.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 104 words
A heat transfer device comprising a convective radiant burner having a gas permeable matrix, a combustible gas plenum chamber having top, side, and end walls with an open bottom, the side and end walls having abutment means, said matrix received in the open bottom and seated against said abutment, a plurality of air knife structures abutting and extending along the outer surface of the side and end walls, means for feeding each air knife structure with air independently of the others to be able to establish in each air knife independent exit velocities, each air knife structure forming a narrow elongated air discharge slot.
Claim 2
Dependent Claim 104 words
A heat transfer device comprising a convective radiant burner having a gas permeable matrix, a combustible gas plenum chamber having top, side, and end walls with an open bottom, the side and end walls having abutment means, said matrix received in the open bottom and seated against said abutment, a plurality of air knife structures abutting and extending along the outer surface of the side and end walls, means for feeding each air knife structure with air independently of the others to be able to establish in each air knife independent exit velocities, each air knife structure forming a narrow elongated air discharge slot.
Claim 3
Dependent Claim 24 words
A heat transfer device as in claim 1 wherein said air knife structures include duct means seated on the top wall of said plenum.
Claim 4
Dependent Claim 46 words
A heat transfer device as in claim 1 wherein said matrix is secured to the plenum by fasteners extending through the side and end walls of the plenum and engaging the matrix, the ends of the fasteners lying at the bottom edge of said plenum walls.
Claim 5
Dependent Claim 22 words
A heat transfer device as in claim 2 wherein said duct means forms a structural support for the knives, plenums and matrices.
