Abstract
A drain removal monitoring equipment for monitoring, in a steam turbine, drain removal performed by drawing a fluid outside at least one hollow stator vane including an internal space into the internal space via a slit formed in a surface of the stator vane includes: a gas-liquid separation device for separating the fluid drawn into the internal space into a liquid phase and a gas phase; a liquid-phase flow measurement device for measuring a flow rate of the liquid phase separated by the gas-liquid separation device; a gas-phase flow measurement device for measuring a flow rate of the gas phase separated by the gas-liquid separation device; a liquid-phase return line through which the liquid-phase flow measurement device and the steam turbine communicate with each other, and a gas-phase return line through which the gas-phase flow measurement device and the steam turbine communicate with each other.
