Axial swirler for a gas turbine burner

摘要

An axial swirler (14b) for a gas turbine burner comprises a vane ring with a plurality of swirler vanes (19b) circumferentially distributed around a swirler axis (11), each of said swirler vanes (19b) comprising a trailing edge (22) In order to achieve a controlled distribution of the exit flow velocity profile and/or the fuel equivalence ratio in the radial direction, said trailing edge (22) is discontinuous with the trailing edge (22) having a discontinuity at a predetermined radius.
