Abstract
Abstract The method of combustion in which fuel is injected at a high velocity through a high pressure air or steam atomizing type burner secured on a cover plate fixed at the front end of the burner tile structure. The fuel stream being deflected to the specific wall of the burner tile structure by Coanda Effect and high temperature combustion gas being induced from the combustion space towards the wall of the burner tile structure opposite the deflected fuel stream and diffused in the fuel stream, the fuel is gasified by heat of the high temperature combustion gas before the stream of fuel is delivered into the combustion space.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
158 words
THE METHOD OF COMBUSTION FOR REDUCING NOX GENERATING RATE COMPRISING; INJECTION OF FUEL, MIXTURE OF FUEL AND STEAM OR MIXTURE OF FUEL AND AIR AT A HIGH VELOCITY THROUGH A HIGH PRESSURE TYPE GAS BURNER OR A HIGH PRESSURE STEAM ATOMIZING TYPE OIL BURNER SECURED ON A COVER PLATE FIXED AT THE FRONT END OF THE BURNER TILE STRUCTURE COMPRISING DEFLECTION OF THE FUEL STREAM TO A SELECTED DIRECTION IN THE BURNER TILE STRUCTURE BY COANDA EFFECT, STABILIZATION OF THE DEFLECTION OF THE FUEL STREAM TO CAUSE THE FUEL STREAM TO FLOW ALONG A SPECIFIC WALL OF THE BURNER TILE STRUCTURE, INDUCTION OF THE HIGH TEMPERATURE COMBUSTION GAS FROM THE THE COMBUSTION SPACE, POSITIONED IN THE BACK OF THE BURNER TILE STRUCTUTE, TOWARDS THE WALL OF THE BURNER TILE STRUCTURE OPPOSITE THE WALL ALONG WHICH THE DEFLECTED FUEL STREAM FLOWS AND DIFFUSION OF THE INDUCED HIGH TEMPERATURE COMBUSTION GAS IN THE FUEL STREAM PROMOTING ENDOTHERMIC GASIFICATION OF FUEL.

Claim 3
Independent Claim
76 words
The method of combustion comprising: injecting fuel from a nozzle through a cover plate, deflecting the injected fuel toward a wall, drawing high temperature combustion gas from a combustion space toward the injected fuel, mixing the combustion gas with the injected fuel, flowing mixed combustion gases and injected fuel toward the combustion space from a space near the wall, adding oxygen to the fuel and combustion gas mixture, and igniting the mixture in the combustion space.
Claim 4
Independent Claim
76 words
The method of combustion comprising: injecting fuel from a nozzle through a cover plate, deflecting the injected fuel toward a wall, drawing high temperature combustion gas from a combustion space toward the injected fuel, mixing the combustion gas with the injected fuel, flowing mixed combustion gases and injected fuel toward the combustion space from a space near the wall, adding oxygen to the fuel and combustion gas mixture, and igniting the mixture in the combustion space.
Claim 5
Dependent Claim
36 words
