Turbine
Abstract: This turbine is provided with: a rotor which comprises a rotary shaft capable of rotating on a shaft line and a moving blade row provided to the outer circumferential surface of the rotary shaft; a casing which covers the rotor from the outer circumferential side and which has a casing inner circumferential surface that extends radially further outward toward the downstream side in the shaft line direction; and an inner circumferential member body which covers the casing inner circumferential surface from the inner circumferential side so as to form a bleeding port on the upstream side between said inner circumferential member body and the casing inner circumferential surface and a discharge port on the downstream side. The bleeding port and the discharge port are each formed in an annular shape centering on the shaft line, and the discharge port has a flow passage cross-sectional area that is set to be smaller than that of the bleeding port.
