Abstract
A radiant heater system of the type having an radiant energy emitter conduit, the radiant heater system comprising an emitter extending at least partly through the area to be heated. The radiant heater system further including a burner for burning fuel thereby forming combustion products, said burner connected to an inlet end of the emitter to inject thermal energy into the emitter and an exhaust end of the emitter serving to exhaust combustion products. The radiant heating system further including 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 wherein the dilution air cools the combustion products proximate said inlet end thereby reduces the emitter temperature proximate said inlet end.
Claims19
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;
- and
- e) 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.
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 as combustion products;
- d) a means for supplying 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;
- e) further comprising a means for lining at least a portion of the interior of said emitter, such that the liner means reduces the heat transferred to the emitter adjacent said liner;
- f) wherein said lining means includes a sheet metal liner formed to lie adjacent a portion of the inner periphery of said emitter;
- and
- g) wherein said sheet metal liner including a smooth outer surface and said emitter having a rougher inner surface to maximize contact resistance between said sheet metal liner and said emitter.
