摘要
In a gas turbine having a structure of collecting a refrigerant after cooling the moving blades, a plurality of wheels having a plurality of moving blades including cooling paths in the outer periphery and a plurality of spacer members are alternately arranged on the rotating axis. A plurality of flow paths through which a refrigerant after cooling the moving blades flows are installed in the spacer members, and the first flow paths interconnect the moving blades arranged on the wheels on the upstream side of gas flow to the downstream side of gas flow of the spacer members, and the second flow paths interconnect the moving blades arranged on the wheels on the downstream side of gas flow to the upstream side of gas flow of the spacer members. The flow paths may be provided with bent parts in the neighborhood of the center of the space members in the axial direction or may be in a linear shape. IMAGE
