Kind Code:
A1
Abstract:
This steam turbine comprises: a stator blade; a rotor blade; a turbine casing accommodating the stator blade and the rotor blade; and a nano water droplet supply device for supplying steam containing atomized water droplets to the turbine casing. The nano water droplet supply device supplies, to main steam, nano water droplets with a D10 particle size of 0.5 μm or less, which is an arithmetic mean of particle sizes of the water droplets, and a mass ratio of not less than 0.01% and not greater than 0.5% with respect to the main steam that flows into the turbine casing.
