ABSTRACT:
In a burner for operating a combustion chamber with a liquid and/or gaseous fuel (12, 16), the combustion air (7) required for this purpose is directed through tangential air-inlet ducts (5, 6) into an interior space of the burner. This directing of the flow results in a swirl flow in the interior space, which swirl flow induces a backflow zone at the outlet of the burner. In order to stabilize the flame front forming there, at least one zone (27) is provided at each sectional body (1, 2) forming the burner, within which zone (27) inlet openings (29) are provided for the injection of supplementary air (32) into the swirl flow (7a). Due to this injection, a film forms at the inner wall of the sectional bodies (1, 2), which film prevents the flame from being able to flashback along the inner wall of the sectional bodies (1, 2) into the interior space of the burner.
