PROBLEM TO BE SOLVED: To restrain unevenness of a combustion condition and uneven deformation of a combustor casing without deteriorating heat efficiency of a gas turbine. SOLUTION: This closed cooling type gas turbine comprises a combustor for burning compressed working fluid and fuel, and a cooling system for cooling a high temperature part of the gas turbine. One part of the working fluid cooling the high temperature part is recovered in the combustor, and one part of the working fluid cooling the high temperature part is recovered to the upstream of the cooling system. Thereby, the closed cooling type gas turbine with high reliability can be provided. COPYRIGHT: (C)2004,JPO
