Abstract
There is disclosed an oxy/fuel burner with a low volume fuel stream. The burner projects a stream of fuel from a fuel orifice and projects an annular stream of oxygen around the stream of fuel from an annular oxygen orifice such that the oxygen velocity to gas velocity ratio is between 1/1 and 3/1, providing a flame whose hottest point is about 5 inches from the fuel orifice.
Claims31
An oxy/fuel burner, comprising:
- fuel means for projecting a stream of fuel from a fuel orifice at a volume of between about 7 SCFH and 15 SCFH of fuel;
- and
- oxygen means for projecting an annular stream of oxygen around said stream of fuel from an annular oxygen orifice surrounding said fuel orifice at an oxygen velocity to gas velocity ratio between about 1/1 and 3/1 such that a flame is produced having a hottest point within about 5 inches of said fuel orifice.
An oxy/fuel burner, comprising:
- fuel means for projecting a stream of fuel from a fuel orifice at a volume of between about 0.5 SCFH and 15 SCFH of fuel;
- oxygen means for projecting an annular stream of oxygen around said stream of fuel from an annular oxygen orifice surrounding said fuel orifice at an oxygen velocity to gas velocity ratio between about 1/1 and 3/1;
- and
- turbulence means for increasing turbulence in at least one of said streams such that a flame is produced having a hottest point within about 5 inches of said fuel orifice.
A method of producing an oxy/fuel flame having a hottest point within about five inches of the base of said flame, said method comprising:
- projecting a stream of fuel from a fuel orifice at a volume of between about 7 SCFH and 15 SCFH of fuel;
- and
- projecting an annular stream of oxygen around said stream of fuel from an annular oxygen orifice surrounding said fuel orifice at an oxygen velocity to gas velocity ratio between about 1/1 and 3/1.
A method of producing an oxy/fuel flame having a hottest point within about five inches of the base of said flame, said method comprising:
- projecting a stream of fuel from a fuel orifice at a volume of between about 0.5 SCFH and 15 SCFH of fuel;
- projecting an annular stream of oxygen around said stream of fuel from an annular oxygen orifice surrounding said fuel orifice at an oxygen velocity to gas velocity ratio between about 1/1 and 3/1;
- and
- increasing turbulence in at least one of said streams.
