PROBLEM TO BE SOLVED: To save energy, improve a strength, prolong a life and decrease the number of repairing and inspecting works, while the transition piece of a combustion device can be easily repaired and replaced by another one. SOLUTION: A gas turbine comprises a compressor 1 for compressing air as working fluid, the combustion device 2 for mixing the compressed air with fuel and burning the mixture to produce combustion gas and a turbine 3 for generating rotating power upon expansion of the combustion gas. The gas turbine further includes a cylindrical liner 5, the transition piece 6 in which the working fluid moves to the turbine 3 from the liner 5, an outlet part 13 of the transition piece 6 having an area parallel to the direction of a rotation axis of the turbine 3, cooling holes 14 whose arrangement intervals are partly widened in the parallel area and a frame part 11 for ensuring a rigidity in the vicinity of the outlet of the outlet part 13. |
