The invention relates to a burner for a turbine, comprising: a flame tube, in which a combustion chamber is formed, a jacket, which encloses the flame tube radially from the outside at a predetermined distance so that an oxidant collection chamber is formed between the flame tube and the jacket, a burner bottom, which bounds the oxidant collection chamber and the combustion chamber at an axial end of the burner, and a swirl generator, which is arranged axially between the flame tube and the burner bottom and axially adjacent to the burner bottom and radially adjacent to the oxidant collection chamber, for feeding a fuel-oxidant mixture into the combustion chamber, wherein the swirl generator has a plurality of guide blades arranged in a circumferential direction of the burner at a circumferential distance from each other so that the distances between the guide blades form a plurality of radial inlet passages to the combustion chamber that each have a tangential component in the course thereof, wherein a fuel supply tube is provided in the inlet flow area of at least some of the inlet passages, which fuel supply tube extends through the respective inlet passage in an axial direction of the burner and transversely to an oxidant flow direction, and wherein each fuel supply tube has at least one fuel outlet opening in the wall thereof, by means of which fuel outlet opening fuel can be mixed into the respective inlet passage with a directional component extending transversely to the oxidant flow direction. |
