Abstract:
A radiant heater system of the type having an radiant energy emitter conduit, the radiant heater system comprising:a) an emitter extending at least partly through the area to be heated;b) a burner means for burning fuel thereby forming combustion products, said burner connected to an inlet end of the emitter to inject thermal energy into the emitter;c) an exhaust end of the emitter serving to exhaust combustion products; and,d) a means for supplying dilution air to combustion products released by said burner means, wherein the dilution means cools the combustion products proximate said inlet end thereby reducing the emitter temperature proximate said inlet end; ande) wherein said dilution mean includes an air intake sleeve for controlling the amount of combustion air available to said burner, and a blower sized to provide dilution air communicating with said burner.
