ABSTRACT:
In a burner for operating a heat generator, 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) form the mixing section of the burner, this mixing section being arranged upstream of a combustion space (30). In the region of the tangential combustion-air-directing inflow ducts (101b-104b), fuel-directing ducts (121-124), the cross section of flow of which is designed for a low-calorific fuel (116), extend along the swirl generator (100). The fuel-directing ducts (121-124) end at a distance upstream of the transition of the tangential inflow ducts (101b-104b) into an interior space of the swirl generator (100), whereby partial mixing between the two media (115, 117) takes place before the mixture flows into the interior space (118). In addition, this setting-back provides sufficient space for other fuel-directing lines (111-114) in this region.
