| 摘要 |
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.
