Abstract: The steam humidifier fed with a premix of natural gas and forced air under low pressure (less than 1 psi) includes a main frame, a movable lower frame, a two part evaporation canister, releasably sealed, for water, an immersible combustion chamber retaining a radiant gas burner and a heat exchanger coupled downstream thereto. The heat exchanger is a coil with an upstream end coupled to the combustion chamber and a downstream end mounted through the upper part of the canister. Maintenance is enhanced by having the lower part of the evaporation tank or canister move downwardly to expose the combustion chamber and the heat exchanger coils. The coils are subject to thermal shock or relatively rapid thermal expansion and contraction which causes scale, adhered thereon, to be released and broken off. A high degree of control and modulation is achieved because the radiant burner is configured for modulated operation from a blue flame mode through a radiant mode.

Abstract: The present invention is a radiant heat deflector assembly for radiating heat on a surface, wherein the assembly includes; a radiant heat source radiating direct emissions, and at least one radiant heat deflector spaced from the heat source. The heat source is so positioned and configured to include radiating direct emissions onto the deflector, the deflector being so positioned, configured and sized as to reflect radiant emissions onto a surface thereby heating the surface. Preferably the heat source adapted to radiate useful direct emissions upwardly towards the deflector and downwardly toward the surface or onto a second deflector such that both direct emissions and reflected emissions heat the surface. Preferably the heat source including an emitter for producing direct radiant emissions and the emitter producing useful direct emissions from both a top surface and a bottom surface of the emitter such that both direct emissions and reflected emissions reach the surface.
