GAS TURBINE

摘要

This gas turbine is configured in a manner so as to obtain rotational power by supplying fuel to compressed air compressed by a compressor (11) at a combustor (12), combusting the fuel, and supplying the generated combustion gas to a turbine (13). A stator vane body (27) and a rotor vane body (28) are disposed in alteration along the direction of flow of the combustion gas inside a turbine cylinder (26) that is formed in a cylindrical shape. The turbine (13) is configured connecting an exhaust diffuser (31) that is formed in a cylindrical shape to the back of the turbine cylinder (26). The rotor vane body (28) is configured disposing a plurality of rotor vanes (28a) at equal intervals in the peripheral direction. By setting the throat width at the edge side in the lengthwise direction of the rotor vanes (28a) to be larger than the throat width at the intermediate section side in the lengthwise direction, it is possible to increase performance by increasing turbine efficiency by performing efficient exhaust gas pressure recovery.
