摘要： In this method of preventing deformation in a turbine casing of a gas turbine, in a turbine casing 10 there is arranged a buffer tank 30. In this buffer tank 30 there are formed a stagnation part agitation air opening 52 which ejects part of the air from an air compressor 21 as stagnation part agitation air Ga2 toward a stagnation part 19 within the turbine casing, and an overall agitation air opening 51 which ejects overall agitation air Ga1 for agitating gas held in an upper space within the turbine casing. In the buffer tank 30 there is provided a partition wall 36 with through holes 53 formed therein serving to resist air from the air compressor 21, in order to make the ejection speed of the overall agitation air lower than the ejection speed of the stagnation part agitation air.

摘要： A compressor rotor includes a first outer cavity formed in a rotor main body and into which air on a high-pressure side of blades is to be introduced, a first inner cavity formed in the rotor main body on an inner side in a radial direction of the first outer cavity; and a first communication passage which connects the first outer cavity and the first inner cavity to each other in the radial direction of the first outer cavity. Along an entire length of the first communication passage from the first outer cavity to the first inner cavity, the first communication passage is inclined toward a forward side of a rotation direction of the rotor main body.

摘要： A shaft sealing device is provided in an annular space between a rotor and a stator surrounding an outer periphery of the rotor, and divides the annular space in the direction of an axis of the rotor into a high-pressure region and a low-pressure region. The shaft sealing device includes a seal body obtained by stacking a plurality of thin plate sealing pieces in a circumferential direction of the rotor; and a high-pressure side plate that extends from the stator toward the radial inner side so as to run along the high-pressure side of the seal body, and is segmented into a plurality of portions in the circumferential direction, and includes a rigidity imparting member configured to impart rigidity in the direction of the axis to a portion of the surface of the high-pressure side plate that faces the high-pressure region.

摘要： In a seal member, a turbine, and a gas turbine, a plurality of vanes includes a vane main body extending in a radial direction of an axis, an outer shroud, an inner shroud and forming a main flow path of a combustion gas between the outer shrouds and the inner shroud, and a retainer protruding from an inner surface in the radial direction of the inner shroud to the inside in the radial direction. The retainers in the vanes, which are adjacent to each other in the circumferential direction, are adjacent to each other in the circumferential direction via a third gap, and relative to one end of the seal member, the other end is positioned downstream in a direction along the axis in the combustion gas to close the third gap.
