Abstract
A gas turbine includes a compressor; a combustor; a turbine configured to drive a rotational shaft of the compressor using combustion gas generated by the combustor; a cooling device configured to generate cooling air by bleeding compressed air from the compressor and cooling the compressed air, and to supply the cooling air to the turbine along the rotational shaft; a pressurizing device configured to increase pressure of the cooling air; a pressurizing device diffuser configured to provide a passage continuing in a turbine circumferential direction, on the outer side in the turbine radial direction to guide the cooling air having the increased pressure to the outer side of the pressurizing device; and a manifold disposed between the pressurizing device diffuser and a plurality of turbine vanes so that a ring-shaped passage communicates with the passage in the pressurizing device diffuser and a cooling passage provided inside each turbine vane.
