Multifuel infrared burner with adjustable metering valve

Abstract

A powered multi-fuel burner has a burner assembly which utilizes an air aspirated nozzle and an infra-red type configuration. An air compressor provides air to the air aspirated nozzle and a fuel tank holds fuel supplied to the air aspirated nozzle by operation of the suction created at the nozzle. A metering valve is interposed between the fuel tank and the air aspirated nozzle. The metering valve is manually adjustable to increase or decrease the fuel supplied to the nozzle thereby to increase or decrease the heat output of the burner.

We claim:  
     
         1 . An infrared burner assembly comprising an air aspirated nozzle, a compressor to provide air to said air aspirated nozzle, a fuel supply to supply fuel to said air aspirated nozzle and a metering valve interposed between said fuel supply and said air aspirated nozzle, said metering valve being adjustable to increase or decrease the fuel supplied to said air aspirated nozzle from said fuel supply.  
     
     
         2 . An infrared burner assembly as in    claim 1    and further comprising a regulator interposed between said metering valve and said fuel supply.  
     
     
         3 . An infrared burner assembly as in    claim 2    wherein said regulator is manually adjustable.  
     
     
         4 . An infrared burner assembly as in    claim 3    wherein said regulator is a zero pressure regulator.  
     
     
         5 . An infrared burner assembly as in    claim 4    wherein said fuel supply is a fuel tank.  
     
     
         6 . An infrared burner assembly as in    claim 5    wherein said compressor is operatively connected to said fuel tank thereby to create a suction in said fuel tank.  
     
     
         7 . An infrared burner as in    claim 6    and further comprising a valve interposed between said compressor and said fuel tank, said valve having a first and second positions, said first position allowing vacuum from said compressor to be applied to said fuel tank, said second position isolating said compressor from said fuel tank.  
     
     
         8 . An infrared burner as in    claim 7    and further comprising a valve interposed between said metering valve and said nozzle, said valve having a first and a second position, said first position allowing fuel to pass to said air aspirated nozzle and said second position isolating said air aspirated nozzle from said fuel tank.
