Combustion device

Claim 2

A combustion device for generating a linear flame comprising: (a) means for combining a combustible gas and a combustion supporting gas, said means comprising an elongated tube having a forward section terminating in a front end, a middle section, and a rearward section, said middle section communicating at its ends with said forward section and said rearward section, respectively, said rearward section being provided with combustible gas and combustion supporting gas intake means; and (b) stalling means for stalling said combined combustible gas and combustion supporting gas, said stalling means comprising a baffle positioned in said forward section, said baffle comprising: (1) a substantially circular inner portion comprising a wire mesh; (2) a generally annular solid portion surrounding said inner portion; and (3) a plurality of radially extending ribs which connect said baffle to the inside wall of said forward section and define a plurality of passageways between said inside wall and said generally annular portion.

Claim 3

A combustion device according to claim 1 wherein said wire mesh comprises stainless steel woven in a plain Dutch weave pattern.

Claim 4

A combustion device according to claim 2 wherein said wire mesh defines a substantially flat surface.

Claim 5

A combustion device according to claim 2 wherein said wire mesh defines a curved surface, the central portion of said curved surface being the portion of said wire mesh closest to the front end of said forward section.

Claim 6

A torch tip comprising: (a) a cylindrical forward section terminating in a front end; (b) stalling means for stalling an air and combustible gas mixture passing through said torch tip, said stalling means being positioned in said forward section and comprising: (1) a baffle comprising a generally circular interior portion including a woven wire fabric; (2) a solid generally annular portion surrounding said fabric; and (3) a plurality of radially extending ribs which extend between said solid generally annular portion and an inside wall of said forward section, said plurality of radially extending ribs defining a plurality of passageways between said inside wall and said solid generally annular portion; (c) a rearward section for receiving combustible gas and air including fuel jet means and an air induction system, the forward end of said rearward section having an axial cylindrical passageway for receiving the air and combustible gas mixture, said passageway having a diameter smaller than the internal diameter of said forward section; and (d) a middle section, including a generally frustoconical portion, communicatively connecting said forward section to said cylindrical passageway and adapted to provide a Venturi effect.

Claim 7

A torch tip comprising: (a) a cylindrical forward section terminating in a front end; (b) stalling means for stalling an air and combustible gas mixture passing through said torch tip, said stalling means being positioned in said forward section and comprising: (1) a baffle comprising a generally circular interior portion including a woven wire fabric; (2) a solid generally annular portion surrounding said fabric; and (3) a plurality of radially extending ribs which extend between said solid generally annular portion and an inside wall of said forward section, said plurality of radially extending ribs defining a plurality of passageways between said inside wall and said solid generally annular portion; (c) a rearward section for receiving combustible gas and air including fuel jet means and an air induction system, the forward end of said rearward section having an axial cylindrical passageway for receiving the air and combustible gas mixture, said passageway having a diameter smaller than the internal diameter of said forward section; and (d) a middle section, including a generally frustoconical portion, communicatively connecting said forward section to said cylindrical passageway and adapted to provide a Venturi effect.

Claim 8

A torch tip according to claim 5 wherein said woven wire fabric comprises stainless steel woven in a plain Dutch weave pattern.

Claim 9

A torch tip according to claim 6 wherein said woven wire fabric defines a substantially flat surface.

Claim 10

A torch tip according to claim 6 wherein said woven wire fabric defines a curved surface, the central portion of said curved surface being the portion of said woven wire fabric closest to the front end of said forward section.

Claim 11

A torch tip according to claim 5 wherein said fuel jet means is axially positioned in said rearward section for injection of combustible gas, the rearward end of said rearward section being adapted to be connected to a source of said gas; and said air induction system comprises apertures for drawing combustion supporting gas into said rearward section to be mixed with said combustible gas in said tube.

Claim 12

A combustion device according to claim 9, wherein at least four said apertures are provided.

Claim 13

A combustion device according to claim 9 wherein the portion of said rearward section forward of said fuel jet means is provided with an axial passageway for receiving and transporting the combustible gas and the combustion supporting gas to said middle section, said axial passageway being of smaller diameter than the internal diameter of said forward section.

Claim 14

A torch tip according to claim 5 wherein said middle section is generally linear.

Claim 15

A torch tip according to claim 5 wherein said middle section is generally arcuate.
