Abstract
A gas turbine combustor includes a diffusion combustor arranged at an axis portion of a combustion chamber for effecting diffusion combustion, a plurality of first premixing combustors arranged at an outer periphery of the diffusion combustor for effecting premixed combustion, each of the plurality of first premixing combustors being formed so that a mixture outlet end thereof projects more downstream than a fuel outlet end of the diffusion combustor, and a plurality of second premixing combustors each formed so that a mixture outlet thereof projects more downstream than the mixture outlet end of the first combustor, wherein the first premixing combustors and the second premixing combustors are arranged alternately at the outer periphery of the diffusion combustor, and wherein a swirler is provided on the first premixing combustor in the vicinity of the mixture outlet end thereof for swirling mixture.
