Abstract
The invention relates to a device for operating an annular combustion chamber (15) which is equipped with combined burners (1) for liquid (4) and gaseous fuels (9), in particular burners of the double-cone design, each burner (1) having a fuel lance (3), with at least one additional air passage (7), for feeding the liquid fuel (4) and an airblast nozzle (2) for atomizing the liquid fuel (4), into which airblast nozzle (2) atomizing air (5) is fed from outside the burner hood (13), and an adjusting mechanism being provided for at least partly throttling the inflow of the atomizing air (5) during gas operation, wherein the adjusting mechanism is an external valve (21) which is arranged in a main feed line (19), coming from the compressor outlet (18), for the atomizing air (5), the main feed line (19) leading into a ring line (20), and the ring line (20) being connected to the head (24) of each fuel lance (3) via one branch line (23) each.
