Rotating Machine
Abstract: This rotary machine comprises: a casing 11 that is hollow inside; a rotor 12 rotatably supported inside the casing 11; a moving blade 14 secured to the outer peripheral section of the rotor 12; a stationary blade 13 that is, in the steam flow direction A1, disposed on the downstream side of the moving blade 14 and that is secured to the inner peripheral section of the casing 11; a seal device 15 disposed between the inner peripheral section of the casing 11 and the leading ends of the moving blades 14; a swirl flow generating chamber 31 provided on the downstream side, in the steam flow direction A1, of the seal device 15 in the casing 11, along the circumferential direction C of the rotor 12; and a plurality of guide members 32 that are provided in the swirl flow generating chamber 31 along a radial direction R of the rotor 12, with prescribed gaps therebetween in the circumferential direction C of the rotor 12. In the swirl flow generating chamber 31, a first wall surface 47, which is on the downstream side in the steam flow direction A1, is positioned on the downstream side in the steam flow direction A1 of a front edge 13a of the stationary blade 13, the front edge 13a being on the upstream side in the steam flow direction A1.
