Abstract
A turbine-cooling system of a gas turbine system includes a first intra-vane flow passage defined in a first stator vane so as to penetrate the first stator vane in a radial direction, a second intra-vane flow passage defined in a second stator vane so as to penetrate the second stator vane in the radial direction, an intra-rotation-shaft flow passage connecting the first intra-vane flow passage and the second intra-vane flow passage in a rotation shaft, an extra-turbine flow passage connecting the first intra-vane flow passage and the second intra-vane flow passage, a boost compressor configured to make cooling air flow sequentially through the first intra-vane flow passage, the intra-rotation-shaft flow passage, the second intra-vane flow passage, and the extra-turbine flow passage, and a cooling unit configured to cool the cooling air.
