Abstract
In a burner for operating a combustion chamber, which burner essentially comprises a swirl generator (100), a transition piece (200) arranged downstream of the swirl generator, and a mixing tube (20), transition piece (200) and mixing tube (20) forming the mixing section of the burner and being arranged upstream of a combustion space (30), there are means (302, 303, 304) in the lower region of the mixing tube (20) which bring about cooling of the base plate (305) forming a front wall. The air quantity (307) used here is passed into the flow (40) of the mixing tube (20). A leaner mixing and lower NOx emissions are thereby achieved.
