Abstract
A combination apparatus having a swirl chamber for mixing primary air and atomized fuel in a primary helical flame vortex and a splitting chamber downstream of the swirl chamber for shearing off secondary helical flame vertexes from the primary vortex rotatably meshed with the prime vortex. Cutting blades positioned in the splitting chamber slice outer portions of the helical primary vortex into channels formed between the blades. The blades are longitudinally disposed perpendicular to the movement of the primary flame vortex and are tilted toward the primary flame vortex at an increasing angle relative to the longitudinal axis between the upstream and downstream portions of the splitting chamber. An intermediate stabilizing chamber can be positioned between the upstream swirl chamber and the downstream splitting chamber.
Claims19
A combustion apparatus including ignition means, a source of pressurized air, and a source of pressurized atomized fuel, said apparatus comprising, in combination:
- a combustor body forming a generally cylindrical combustor chamber having an upstream end and a downstream end and a longitudinal axis extending between said upstream and downstream ends, said body including an upstream end first combustor portion forming a generally dome-shaped first chamber and a downstream end second combustor portion having a generally cylindrical wall forming a second chamber, said first chamber and said second chamber comprising said combustor chamber,
- said first combustor portion forming first passage means for passing a first portion of said pressurized air and said pressurized fuel into said said first chamber, said first combustor portion including deflector means associated with said first passage means for directing said first portion of said air in a first rotational direction into a fuel/air mixture of generally helical configuration adapted to being ignited into a helical primary flame vortex about said longitudinal axis,
- a plurality of approximately parallel evenly spaced blades extending into said second chamber, said blades having bases connected to said cylindrical wall of said second chamber and forming a plurality of channels therebetween, said blades being adapted to split away the outer portion of said primary flame vortex and to direct said outer portion into a plurality of secondary flame vortexes of generally helical configuration in said channels in a second rotational direction about said primary flame vortex, said blades being disposed approximately perpendicular to said first rotational direction of said primary flame vortex and disposed toward said first rotational direction at an angular tilt measured from said bases of said blades relative to radii extending to a tangential plane at said bases of said blades at said cylindrical wall of said second chamber, and
- second passage means formed in association with said cylindrical wall of said second combustor portion and with said plurality of blades and being for passing a second portion of said pressurized air into said second chamber into mixture with said plurality said secondary flame vortexes.
