Abstract

In a burner which essentially comprises a swirl generator (100) for a combustion-air flow (115) and means for injecting a fuel into the combustion-air flow (115), a mixing section (220) is arranged downstream of the abovementioned swirl generator. This mixing section (220) has inside a first part (200) of the section a number of transition passages (201) which run in the direction of flow and ensure the smooth passing of the flow: (40) formed in the swirl generator t (100) into a mixing tube (20) arranged downstream. The outlet plane of this mixing tube (20) to the combustion chamber (30) is designed with a breakaway edge which serves to stabilize and enlarge a backflow zone (50) forming downstream. A number of mixing elements (300) are provided concentrically to the mixing section (220) , which mixing elements (300) serve to form a mixture (304) of combustion air (115a) and a fuel (303). This mixture (304) from the respective mixing element (300) then forms in each case a pilot stage of the combustion chamber (30).
