To displace a flame moved to a mixing region of a fuel nozzle by reducing a trend of stabilizing a burning flame in the nozzle.
Air inlet slots 36, 38 are formed between superposed ends of two offset cylindrical arc-like scroll members 22, 24 of a tangential air inlet fuel nozzle 10. An end plate 18 has a combustor inlet port 20, and the other end plate 16 seals a flowing region of the nozzle. The members 22, 24 are fixed between the end plates. A central body 12 is provided between the members coaxial with a longitudinal axis 26. The body has a base 58 and an inner passage 64. The base 58 has at least one air supply hole extended through the base. The body 12 has a truncated conical part 86 and an aerodynamic ramp, which prevent backflow and flame stability between the end plates.
