Abstract
In a mixing and flame stabilization appliance in a combustion chamber with premixed combustion, a gaseous and/or liquid fuel is introduced into the combustion air. The combustion air is guided via a plurality of vortex generators (9) arranged adjacent to one another over the width or the periphery of the combustion chamber duct (20) through which flow takes place. Fuel is introduced into the duct (20) in the immediate region of the vortex generators (9). A vortex generator (9) has three surfaces around which flow can take place freely, which surfaces extend in the flow direction, one forming the top surface (10) and the two others forming the side surfaces. The side surfaces enclose between them a V-angle (a) varying in the flow direction and the top surface (10) is disposed at an angle of incidence to the duct wall (21 ) which varies in the flow direction. Thorough mixing of the combustion air and the fuel can be achieved within the shortest distance by means of such vortex generators and the flame can be aerodynamically stabilized at the same time.
