ABSTRACT:
An infrared energy generator, which is capable of effective operation when provided with fuel from a relatively low pressure supply, such as from a relatively mobile liquid propane tank, to radiate infrared energy over a relatively large output area, has an orifice plate in the plenum to impede fuel flow to the fuel output where combustion occurs. The orifice plate has openings therethrough to conduct fuel from one portion of the plenum, which is coupled to the fuel supply at a fuel input orifice, to another portion of the plenum, which leads to the fuel output, and the sum total of the cross-sectional areas of the openings in the orifice plate is smaller than the cross-sectional area of the fuel input orifice so that a back pressure is created in the one plenum portion to assure fuel flow at a suitable velocity in a positive direction toward the other plenum portion and subsequently to the fuel output, thereby to reduce or to eliminate the possibility of encountering a blow out or a backfire during operation.
