to the second air blast nozzle portion 15 b past the air passage 20 the pressurized air supplied to the first air blast nozzle portion 15 a is injected to the outside while being swirled because of the inclination of the air passage 16 thereby forming an air blast running along the inner surface of the film of the liquid fuel injected in an annular liquid film state from the liquid nozzle portion 14 the pressurized air supplied to the second air blast nozzle portion 15 b is injected to the outside while being swirled by the swirlers 21 thereby forming an air blast running along the outer surface of the film of the liquid fuel injected in an annular liquid film state from the liquid nozzle portion 14 as shown above air blasts are formed along the inner and outer surfaces of the film of the liquid fuel injected in an annular liquid film state from the liquid nozzle portion 14 thus the atomization and evaporation of the liquid fuel are promoted to obtain a satisfactory state of combustion thus even if an operation at a high pilot ratio is performed to ensure combustion stability for example during a light load operation of the gas turbine the occurrence of smoke black smoke can be kept down in the present embodiment the air passage 16 which supplies pressurized air to the first air blast nozzle portion 15 a formed as a horizontally elongated cavity at the center of the nozzle body 11 is branched into a plurality of sections in the circumferential direction of the nozzle body 11 similarly the gas.
