Abstract

PURPOSE: To preclude the inflow of scales into a steam turbine by a method wherein a scale collector, a chamber and a scale discharging piping are provided at a steam inlet portion of a cylinder for a steam strainer which separates bulky scales.
CONSTITUTION: A strainer 10, separating bulky scales mixed in steam fluid, has holes 10a for passing the steam and is held in a cylinder 11. A scale collector 14 and a chamber 17 are provided at a steam inlet portion 4 and the bulky scales collected in the chamber 17 can be discharged to the outside of a valve by connecting a scale discharging piping 19. The steam, scales therein are separated therefrom, passes through the holes 10a, 11a for passing the steam and a throat portion 27, consisting of a valve seat 16 and a sleeve 6, and arrives at a steam chamber 15 and a steam outlet portion 5. Thereby, inflow of the scales can be precluded.
