Abstract (en)
The present invention is related to calibration means (1) of a swirler (20) for a gas turbine burner. The swirler (20) comprises a plurality of vanes (21) and a plurality of mixing channels (22) between the vanes (21), wherein each mixing channel (22) is enabled to channel air from a radially outer end (24) of the mixing channel (22) to a radially inner end (23) of the mixing channel (22). The calibration means (1) can be arranged at the swirler (20) in such a way that it defines exactly the flow of the channelled air in the mixing channels (22).
