PROBLEM TO BE SOLVED: To provide a steam turbine which can improve the efficiency of a turbine by reducing a supersaturation loss.SOLUTION: A steam turbine 10 of this embodiment comprises: a casing 20 penetrated with a turbine rotor 22; a moving blade 21 implanted in the turbine rotor 22; and a static blade 25 which forms a turbine paragraph together with the moving blade 21, and is supported between a diaphragm outer ring 23 and a diaphragm inner ring 24 which are arranged inside the casing 20. Furthermore, the steam turbine 10 comprises: an injection part group 30 composed of a plurality of injection parts 31 which are arranged in the radial direction of a steam passage 29 in which steam in the casing flows, and inject microparticles; a microparticle supply part 40 which supplies microparticles to the injection part group 30; and a control part 50 which controls the injection of the microparticles at each injection part 31 by controlling the microparticle supply part 40. |
