Abstract In the dual burner of a gas turbine or a hot gas generating system, the swirler (1) is formed from at least two doubly curved sheets (4, 5) subject to tangen- tial air inlet (7). These sheets (4, 5) are folded along diagonals (10a, 10b) running conically outwards in the outlet flow direction. One curved fold face forms an inner cone (4b, 5b) expanding in the outlet flow direction while the other curved fold faced forms an outer cone (4a, 5a) which contracts in the outlet flow direction. The inner cones (4b, 5b) each carry at their ends a fuel main (8) whose fuel nozzles (9) are directed towards the inner zone of the swirler (1). The liquid fuel (2a, 2b) is directed onto the outer cone (4a, 5a), the oil film (6) forming there being "rolled in" by the air (7) flowing into the outer cone (4a, 5a). (Figures 1, 2, 3)
