    摘要： The present invention relates to an improvement of a turbine blade in a gas turbine and, more particularly, to a cooling structure of the turbine blade. The turbine blade comprises a hollow-structured main body (2) and cooling medium discharging device (3) located in the inner cavity of the hollow-structured main body (2) and formed to discharge a cooling medium from the surface thereof, so that the cooling medium discharged from the cooling medium discharging device (3) impinges against the inner surface of the main body (2) to remove the heat from the same. The turbine blade further includes a projection (9) which is formed on the inner surface of the leading edge (8) of the main body (2), extending along the spanwise direction of the blade, and the cooling medium discharging device are formed to allow at least part of the cooling medium to directly impinge against proximal portions of the projection (9). With this arrangement, the invention can provide a turbine blade which allows a small amount of cooling air to cool the turbine blade and its leading edge (8) in particular with great effectiveness.

    摘要： A turbine comprising a casing in which are disposed a turbine rotor assembly which provides a plurality of turbine blades and a guide vane assembly which provides a plurality of guide vane segments, and there being shrouds spaced from turbine blade tips. To control the clearance between the turbine blade tips and the shrouds at a small value by simple structure, the guide vane segments are made movable freely in the radial direction and inside parts of the guide vane segments are fixed to a stationary member.

    摘要： A gas turbine includes a rotor shaft comprising a plurality of discs (8, 9, 10, 11, 12a). Each disc (8, 9, 10, 11, 12a) has a plurality of moving blades (4, 5, 6, 7, 7a) driven by combustion gas and arranged annularly on the peripheral portion. Spacers (11a, 13, 14, 15) are arranged between the discs (8, 9, 10, 11, 12a), the respective discs (8, 9, 10, 11, 12a) and the spacers (11a, 13, 14, 15) being arranged in the axial direction. The moving blades (4, 5, 6, 7, 7a) are provided with flow paths (8a, 9a) for introducing coolant for cooling and discharging the coolant heated by the combustion gas. Contact surfaces (16a, 31, 32, 33, 34, 35, 36) contacting both the discs (8, 9, 10, 11, 12a) in rotor peripheral side regions and adjacent spacers (11a, 13, 14, 15) are formed therebetween. A supply flow path (8a) passes through the discs (8, 9, 10, 11, 12a) and the spacers (11a, 13, 14, 15) in the regions forming the contact surfaces (16a, 31, 32, 33, 34, 35, 36) and supply the coolant for cooling the moving blades (4, 5, 6, 7, 7a). A recovery flow path (9a) recovers the coolant which is heated by the moving blades (4, 5, 6, 7, 7a).

    摘要： A high efficiency coolant collection type gas turbine is obtained by forming coolant supply and collection flow paths for moving blades in a more outer peripheral side of a gas turbine rotor than a hub, supplying the coolant supplied from a shaft end into the moving blades through the supply flow path, collecting the coolant after cooling into a combustion chamber side, on the other hand, supplying air extracted from a compressor to cool moving blades of downstream side stage or a rotor outer wall through slits formed from a turbine rotor central portion to the hub, reducing rotor thermal stress and a pressure loss of the coolant flow paths and cooling a high stage side of a compressor rotor.
