Abstract:
1. Apparatus for the highly efficient mixing of gaseous fuel and air prior to combustion; said apparatus comprising a swirler having a plurality of blades, each blade having internal conduits that direct fuel through the interior of the blade to through holes on the surface of the blade; so that, in operation, fuel is injected into the air stream directly from the surface of the blades in a direction that is perpendicular or approximately perpendicular to the surface of the blades, and that is opposite or approximately opposite in direction to the oncoming air stream; as air enters the swirler, at least some of the air is swirled by the blades; the swirled air encounters injected fuel in a cross-flow direction, inducing eddies of air and fuel that enhance mixing and that enhance flame stability when the air-fuel mixture is burned.
