Zusammenfassung:Burner system having turbulence elements The invention relates to a burner system (2, 3), especially for use in a gas turbine, having an annular channel (6, 13) for the supply of combustion air, wherein the annular channel (6, 13) has an axis of symmetry (12), a fuel duct (4, 5, 19, 20, 21) for the supply of fuel, a plurality of turbulence elements (29) for generating highly turbulent combustion air and an inlet for fuel (10, 11, 15, 16, 17) from the fuel duct (4, 5, 19, 20, 21) into the annular channel (6, 13) down- stream of the turbulence elements (29), wherein carrier elements (30) of the turbulence elements (29) extend in the radial direction and at least one wing (31) is arranged on each of the carrier elements (30), wherein the projection of a wing (31), which is arranged radially toward the outside with respect to the axis of symmetry (12), onto a cross-sectional area of the annular channel (6, 13) is greater than the projection of a wing (31) which is arranged radially toward the inside with respect to the axis of symmetry (12).
