Abstract

A gas burner assembly for a gas turbine has a first, premix, burner (5), and a second burner (4) surrounded by the first burner (5); the second burner has a swirler (16) with vanes (21), a channel (40, 55) for feeding combustion air into the gaps (22) in the swirler (16), and at least a first gas feed line (52) for feeding a stream of fuel gas into the gaps (22); the first gas feed line (52) has an outlet (51) designed to generate a premix pilot flame, and the channel (40) has a number of calibrated-section choke holes (56) for setting combustion air flow to the swirler (16).
