ABSTRACT:
An induced draft warm air furnace employing a radiant infrared burner. The use of a radiant burner results in a very low concentration of oxides of nitrogen (NO.sub.X), in the combustion gases produced. In addition, the use of a radiant burner eliminates the combustion roar produced by other types of burners found in similar furnaces. Further, the invention allows the attainment of the advantages of a radiant burner in a furnace of otherwise standard design with only minor modification. The scope of the invention includes the use of the radiant burner within a combustion chamber which is either within the heat exchanger enclosure and joined to the heat exchanger or within a burner box mounted external to the heat exchanger enclosure but having means for the free passage of combustion gases from the combustion chamber to the heat exchanger. The use of induced draft eliminates the possibility of combustion gases leaking out of the combustion chamber or heat exchanger.
