Abstract
In a burner for operating a combustion chamber, which burner essentially comprises a swirl generator (100) and a mixing section (220) arranged downstream of the swirl generator, this mixing section acting upstream of a combustion chamber (30), the swirl flow induced by the swirl generator (100) is directed via transition passages (201) into the mixing section (220). At the outlet of a mixing tube (20) belonging to the mixing section (220), the burner front (70) of the mixing tube (20) is provided with at least one torus-like notch (71) on the combustion-chamber side. Thus the stability of the backflow zone (50) can be intensified, which has a positive effect on the combustion from all aspects.
