A burner for a turbine has a flame tube, a casing enclosing the flame tube forming an oxidant collection chamber, a burner bottom which bounds the oxidant collection chamber and the combustion space, and a swirler which has a plurality of guide vanes arranged so that the distances between the guide vanes form a plurality of radial inlet passages to the combustion space. A fuel supply pipe is provided in the inlet flow region of at least some of the inlet passages, which fuel supply pipe extends lengthwise through the respective inlet passage in an axial direction of the burner and traverse to an oxidant flow direction, and wherein each fuel supply pipe has in its wall at least one radial fuel output opening by which fuel can be mixed into the respective inlet passage with a directional component extending transverse to the oxidant flow direction. |
