One shot heat exchanger burner

Abstract

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 bumer, 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:

       2 . The combination of  claim 1 , wherein said burner has a mixing chamber for receipt therein of combustible gas, said mixing chamber communicating with said burner face.  
   
   
       3 . The combination of  claim 2 , wherein said burner comprises spaced walls defining said mixing chamber.  
   
   
       4 . The combination of  claim 3 , 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.  
   
   
       5 . The combination of  claim 2 , wherein said controlling means at said burner face comprises a plurality of individual flow passages for passing said combustible gas therethrough.  
   
   
       6 . The combination of  claim 5 , wherein said flow passages are defined by a plurality of spaced fins.  
   
   
       7 . The combination of  claim 6 , 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.  
   
   
       8 . The combination of  claim 6 , wherein said fins are defined by a single continuous strip of material formed in ribbon fashion.  
   
   
       9 . The combination of  claim 8 , wherein said fins are arranged in separate sections of ribboned fins.  
   
   
       10 . A hot air furnace, comprising: 
 a furnace outer covering,    a plurality of heat exchangers supported within said covering in spaced arrangement, each heat exchanger having an inlet port and an outlet port;    a unitary burner for producing combustion gases, said burner having a burner face for passing therethrough a combustible gas, said burner being supported within said covering with said burner face being disposed adjacent to and in fluid communication with all of said heat exchanger inlet ports, means for controlling the flow of the combustion gases at said burner face, whereby combustion gases may flow from the burner into each of the inlet ports of said heat exchangers;    a blower adapted to blow air over the heat exchangers; and    an induction blower in fluid communication with the outlets of said heat exchangers adapted to draw the combustion gases through the heat exchangers and discharge such combustion gases outwardly from the furnace outer covering.    
   
   
       11 . A hot air furnace according to  claim 10 , wherein said burner comprises spaced walls defining a mixing chamber, said mixing chamber communicating with said burner face.  
   
   
       12 . A hot air furnace according to  claim 11 , wherein said burner comprises a venturi tube supported by one of said burner walls, said venturi tube having an interior opening communicating with said mixing chamber.  
   
   
       13 . A hot air furnace according to  claim 11 , further including a support frame supported by walls of said burner adjacent to and substantially around the burner face.  
   
   
       14 . A hot air furnace according to  claim 13 , further including an igniter supported by said support frame between said burner face and the inlet ports of said heat exchangers.  
   
   
       15 . A hot air furnace according to  claim 14 , wherein said controlling means at burner face comprises a plurality of individual flow passages for passing said combustible gas therethrough.  
   
   
       16 . A hot air furnace according to  claim 15 , wherein said flow passages are defined by a plurality of spaced fins.  
   
   
       17 . A hot air furnace according to  claim 16 , 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.  
   
   
       18 . A hot air furnace according to  claim 17 , wherein said fins are defined by a single continuous strip of material formed in ribbon fashion.  
   
   
       19 . A hot air furnace according to  claim 18 , wherein said fins are arranged in separate sections of ribboned fins.
