Abstract
In a combustion apparatus having an ignition means, a plurality of first swirl vanes positioned at the upstream end of a flame retention head creates a helical primary air/fuel mixture in the combustion chamber of the retention head that ignites into a primary flame vortex. A second plurality of vanes mounted on the inner walls of the retention head shears the outer portions of the primary flame vortex into a plurality of secondary helical flame vortexes disposed about the perimeter of the primary flame vortex. The secondary flame vortexes are opposite in rotational orientation to the direction of rotation of the primary flame vortex. Secondary air is injected into the combustion chamber at the area of shearing.
Claims18
Combustion apparatus including ignition means, a source of pressurized air, and a source of pressurized atomized fuel, said apparatus comprising:
- a flame retention head forming a cylindrical combustion chamber having an upstream end and a downstream end and a longitudinal axis extending between said upstream and downstream ends,
- first passage means including first deflector means for passing a first portion of said pressurized air and said pressurized fuel into said upstream end of said combustion chamber, said first deflector means being for directing said air and said fuel in a first rotational direction into a fuel/air mixture of helical configuration adopted to being ignited into a primary flame vortex about said longitudinal axis,
- second deflector means mounted about the inner surface of said combustion chamber downstream of said first deflector means, said second deflector means being for shearing away the outer portions of said primary flame vortex and directing said outer portions into a plurality of secondary flame vortexes of helical configurations directed in second rotational directions opposed to said first rotational direction and disposed about said primary flame vortex, and
- second passage means formed in said flame retention head disposed in association with said second deflector means and being for passing a second portion of said pressurized air into said combustion chamber into mixture with said plurality of said secondary flame vortexes.
