A burner for a turbine, comprising: a flame tube, in which a combustion chamber is formed, a jacket which from radially outside encloses the flame tube at a predetermined spacing thereof, so that between flame tube and jacket an oxidising agent collection space is formed, a burner base, which delimits the oxidising agent collection space and the combustion chamber at an axial end of the burner, and a swirl generator, which, axially adjoining the burner base and radially adjoining the oxidising agent collection space, is axially arranged between the flame tube and burner base for feeding a fuel oxidising agent mixture into the combustion chamber, wherein the swirl generator comprises a plurality of guide vanes each arranged along a circumferential direction of the burner arranged circumferentially spaced from one another, so that the respective spacings between the guide vanes form a plurality of radial inlet passages towards the combustion chamber each comprising a tangential component in their course, wherein in a respective inlet flow region at least of some of the plurality of inlet passages a fuel feed tube (43a, 43b, 43c, 43d) is provided in each case, which with respect to its length extends in an axial direction of the burner and transversely to an oxidising agent flow direction through the respective inlet passage, and wherein each fuel feed tube (43a, 43b, 43c, 43d) in its wall comprises at least one fuel output opening (44, 45) which is radial with respect to the fuel feed tube (43a, 43b, 43c, 43d), via which fuel can be admixed into the respective inlet passage with a directional component running transversely to the oxidising agent flow direction, characterized in that at least one of the fuel feed tubes is arranged out of centre in the respective inlet passage with respect to the longitudinal centre axis of the respective inlet passage. a flame tube, in which a combustion chamber is formed, a jacket which from radially outside encloses the flame tube at a predetermined spacing thereof, so that between flame tube and jacket an oxidising agent collection space is formed, a burner base, which delimits the oxidising agent collection space and the combustion chamber at an axial end of the burner, and a swirl generator, which, axially adjoining the burner base and radially adjoining the oxidising agent collection space, is axially arranged between the flame tube and burner base for feeding a fuel oxidising agent mixture into the combustion chamber, wherein the swirl generator comprises a plurality of guide vanes each arranged along a circumferential direction of the burner arranged circumferentially spaced from one another, so that the respective spacings between the guide vanes form a plurality of radial inlet passages towards the combustion chamber each comprising a tangential component in their course, wherein in a respective inlet flow region at least of some of the plurality of inlet passages a fuel feed tube (43a, 43b, 43c, 43d) is provided in each case, which with respect to its length extends in an axial direction of the burner and transversely to an oxidising agent flow direction through the respective inlet passage, and wherein each fuel feed tube (43a, 43b, 43c, 43d) in its wall comprises at least one fuel output opening (44, 45) which is radial with respect to the fuel feed tube (43a, 43b, 43c, 43d), via which fuel can be admixed into the respective inlet passage with a directional component running transversely to the oxidising agent flow direction, characterized in that at least one of the fuel feed tubes is arranged out of centre in the respective inlet passage with respect to the longitudinal centre axis of the respective inlet passage.
