ABSTRACT:
In a burner (100) which essentially comprises at least two hollow, conical sectional bodies (101, 102) nested one inside the other in the direction of flow, the respective longitudinal symmetry axes (101b, 102b) of the sectional bodies (101, 102) run mutually offset in such a way that the adjacent walls of the sectional bodies (101, 102) form air-inlet slots (119, 120), tangential in their longitudinal extent, for a combustion-air flow (115) in the interior space (114) of the burner. The cross section of flow of these tangential air-inlet slots (119, 120) decreases in the direction of flow of the burner (100) in such a way that this has a positive effect on stabilization of the backflow zone (106) at the outlet of the burner (100).
