Abstract
In a method and a device for burning fuels in a combustion air main stream, the combustion air is passed in a channel over at least one deltoid body. The deltoid body consists of at least one essentially triangular vortex generator area and a downstream, trapezoid flame stabilizer area. In the region of the vortex generator area, fuel is introduced into the turbulent combustion air. The vortex generator area is set via a half sweep angle and an angle of attack relative to the main stream in such a way that the spin of the longitudinal vortexes induced in the main stream is smaller than the critical spin for generating a recirculation zone. The flame stabilization area is set via a half sweep angle and an angle of attack relative to the stream in such a way that the spin of the longitudinal vortexes induced in the stream is greater than the critical spin, so that for each deltoid body, a pair of concave recirculation zones is generated, and the ignited combustion air-fuel mixture is stabilized.
