The invention relates to a burner for a gas turbine, comprising a burner lance (58, 72) and/or burner hub (94), a burner passage (60, 68, 100) which at least partially surrounds said burner lance and/or burner hub, and a fuel supply arrangement (73) comprising at least one fuel nozzle (80, 80a, 80b) and at least one fuel channel (82). The burner allows pollutant emissions to be reduced and offers a high degree of operational safety. According to the invention, the fuel supply arrangement comprises a fluidic oscillator (24a, 25, 85) that has an interaction chamber (26), said interaction chamber comprising at least one inlet (28) and, lying opposite, one outlet region (32) that has at least one outlet channel (34, 36), one end of at least one feedback line terminating into the interaction chamber in the region of the inlet, the other end thereof terminating into the outlet region or into an outlet channel (34, 36), and each end of said feedback line being sealed off from the interaction chamber by a flexible membrane (37). |
