One shot heat exchanger burner
View Patent ↗A single burner, heat exchanger combination for particular use in a hot air furnace, includes a plurality of spaced heat exchangers, each heat exchanger having an inlet port for receipt therein of combustion gases. A unitary burner for producing combustion gases includes a burner face defined by a plurality of spaced fins for passing therethrough a combustible gas. The inlet ports of each of the heat exchangers are disposed adjacent to and in fluid communication with the passages defined by the burner face fins. A hot air furnace comprising the single burner, heat exchanger combination also includes a blower adapted to blow air over the heat exchangers and an induction blower in fluid communication with the outlets of the heat exchanger adapted to draw the combustion gases through the heat exchangers and to discharge such combustion gases outwardly from the furnace. An igniter is disposed on a support frame around the burner face for igniting the combustible gas flowing through the burner face fins for flow of combustion gases through the heat exchangers.
1. A single burner, heat exchanger combination for a fuel-fired furnace, comprising:
a plurality of spaced heat exchangers, each heat exchanger having an inlet port for receipt therein of combustion gases; and
a unitary burner for producing combustion gases, said burner having a continuous burner face for passing therethrough a combustible gas and a mixing chamber for receipt therein of combustible gas, said mixing chamber communicating with said burner face, said burner face being defined by a plurality of spaced apart fins, said fins extending continually along said burner face, aid inlet ports of each heat exchanger being disposed adjacent to and in fluid communication with said burner face, whereby combustion gases may flow from between the fins of said burner face and into each of the inlet ports of said heat exchangers.
2. The combination of claim 1 , wherein said burner comprises spaced walls defining said mixing chamber.
3. The combination of claim 2 , wherein said burner comprises a venturi tube supported by one of said walls, said venturi tube having an interior opening communicating with said mixing chamber.
4. The combination of claim 1 , wherein said fins are spaced by one or more bosses disposed on selected fins, the height of said bosses being selected to provide desired fin spacing.
5. The combination of claim 4 , wherein said fins are defined by a single continuous strip of material formed in ribbon fashion.
6. The combination of claim 5 , wherein said fins are arranged in separate sections of ribboned fins.
