Gas pressure regulated atomizer tip for gas/oil burner
Abstract
Abstract A BURNER SUITABLE FOR FIRING A GASEOUS FUEL OR A COMBINATION OF A GASEOUS AND A LIQUID FUEL WITH THE GAS BEING USED TO ATOMIZE THE LIQUID FUEL. PRIMARY GAS IS INTRODUCED TANGENTIALLY INTO THE OIL STREAM IN THE THROAT OF A VENTURI NOZZLE DESIGNED TO EXPAND THE MIXTURE. SECONDARY GAS DISCHARGES THROUGH AN OUTER ANNULUS AND IMPINGES ON THE GAS-OIL MIXTURE DISCHARGING FROM THE VENTURI NOZZLE. THE SIZE OF THE ANNULUS FOR ADMITTING THE SECONDARY GAS IS RENDERED ADJUSTABLE BY AUTOMATICALLY MOVING THE OIL ATOMIZING NOZZLE IN AND OUT OF SAID ANNULUS, SO AS TO MAINTAIN CONSTANT GAS PRESSURE IN THE PRIMARY GAS TUBE AT ALL GAS INLET RATES. THE VELOCITY OF THE MIXTURE DISCHARGING FROM THE NOZZLE WILL THEN BE CONSTANT AT ALL GAS FLOW RATES. THE BURNER HAS GIVEN EXCELLENT RESULTS IN ATOMIZING FUEL OIL WITH GAS FLOWS AS LOW AS 17% OF THE TOTAL B.T.U. FIRED AT A HIGH FIRING RATE (30 G.P.H. OIL EQUIVALENT TOTAL FUEL IN THE CASE OF THE BURNER TESTED), AND ALSO WITH 50% GAS AT A LOW FIRING RATE (10 G.P.H. EQUIVALENT TOTAL FUEL).
