PREMIXED BURNER FOR A GAS TURBINE COMBUSTOR

摘要

The disclosure relates to a burner (1) for a single combustion chamber or first combustion chamber of a gas turbine, with an injection device (7) for the introduction of at least one gaseous and/or liquid fuel into the burner (1), wherein the injection device (7) has at least one body (22) which is arranged in the burner (1) with at least one nozzle (15) for introducing the at least one fuel into the burner (1), wherein the at least one body (22) is located in a first section (18) of the burner (1) with a first cross-sectional area at a leading edge of the at least one body (22) with reference to a main flow direction (14) prevailing in the burner (1), wherein downstream of said body (22) a mixing zone (2) is located with a second cross-sectional area, and at and/or downstream of said body (22) the cross-sectional area is reduced, such that the first cross-sectional area is larger than the second cross-sectional area.
