Abstract A BURNER CAPABLE OF OPERATING ON A GASEOUS AND A LIQUID FUEL SEPARATELY AND IN COMBINATION WITH EACH OTHER TO PRODUCE A FLAME WHICH HAS A GREATER EXTENT IN LATERAL DIRECTIONS THAN IN AN AXIAL DIRECTION.

THE FLARED SECTION OF THE TUNNEL IS SYMMETRICAL IN LATERAL PLANES AND IS SMOOTHLY CONTOURED INTO THE INNER PLANAR SURFACE OF THE WALL. A CONICAL STREAM OF LIQUID FUEL PARTICLES IS INJECTED INTO THE SMALL END OF THE FLARED SECTION SO THAT ITS CONICAL ANGLE IS SUBSTANTIALLY TANGENT TO THE SURFACE OF THE MIDSECTION OF THE FLARED SECTION. SURROUNDING THE LIQUID FUEL SUPPLY TUBE IS A GASEOUS SUPPLY TUBE FOR SUPPLYING AN ANNULAR COLUMN OF GASEOUS FUEL TO THE ENTRANCE OF THE FLARED SECTION. MEANS ARE PROVIDED FOR SUPPLYING HELICALLY SWIRLING ANNULAR COLUMN OF COMBUSTION AIR ADJACENT THE TUNNEL SURFACE AROUND THE FUEL STREAM OR STREAMS.
