MOISTURE SEPARATOR OF STEAM TURBINE AND STEAM TURBINE STATOR VANE

摘要

PROBLEM TO BE SOLVED: To provide a moisture separator and a steam turbine stator vane which can reduce accompanied steam amount to effectively remove a liquid film.SOLUTION: To remove a liquid film formed on a face of a stator vane, the stator vane has a hollow structure. When a slit provided on the face of the vane reduces the pressure in the hollow structure to suction the liquid film, an opening of the slit is covered by a mesh-like sheet having micro grid.
