PROBLEM TO BE SOLVED: To provide a gas turbine combustor superior in durability, and excellent in an emission characteristic. SOLUTION: This gas turbine combustor 1 has a combustion cylinder 2, a premixing pipe 3 and a fuel supply means 5. In the fuel supply means, fuel is supplied to an annular fuel passage 16 in the tangent direction, and is uniformly injected from an annular nozzle part 19, and is atomized by air from a peripheral air passage 22 for surrounding the nozzle part, and makes an axial directional flow in the combustor. The air flowing inside from a hole 25 of a peripheral wall surface of the premixing pipe makes a swirling flow of surrounding the axial directional flow in the combustor. A flame is held in a position separate from a top part of the combustor, and a heat shielding plate 6 is not overheated, and the durability is improved. COPYRIGHT: (C)2009,JPO&INPIT
