PROBLEM TO BE SOLVED: To adopt an air blast system for a pilot nozzle in a dual fuel burning low-NOx combustor to restrain smoke from being generated in a low-load operation of a gas turbine, or the like. SOLUTION: In the gas turbine provided with this dual fuel burning low-NOx combustor having the pilot nozzle 10 capable of injecting concurrently or selectively gas fuel and liquid fuel, and a plurality of main nozzles arranged in the periphery of the pilot nozzle to inject concurrently or selectively the gas fuel and the liquid fuel, the pilot nozzle has a gas nozzle part 13 for injecting the gas fuel, and a liquid nozzle part 14 for injecting the liquid fuel, the air blast system is adopted in the liquid nozzle part, burning air is used as air blast, the burning air is collided with a liquid film formed in the liquid nozzle part, and the liquid fuel is atomized using a velocity difference therein.
