Abstract (en)
Burner (01) for a combustor of a gas turbine, the burner (01) comprising in fluid flow sequence a swirler section (02) and a mixing section (12) and an outlet section (32) generally arranged around a burner axis (10). At the swirler section (02) air and fuel are introduced into the burner (01). The mixing section (12) is downstream of the swirler section (02) and comprises a tube (24) and defines a mixing volume (13) to mix the stream of air and fuel. The outlet section (32) comprises an annular bulge (34) and a burner outlet (33) therein to introduce the mixed stream of air and fuel into a combustion chamber. To enhance the mixing of air and fuel the mixing section (12) further comprises a sleeve (14) inside the tube (24) so that an annular channel (23) is defined between the sleeve (14) and the tube (24).
