Abstract

PURPOSE: To improve the turbine efficiency by reducing the steam leakage through the gap between TH the head of the rotary blade and the inner surface of the casing or the outer ring of the stationary blade by the work of a sealing device at the head of the blade wherein provided the multiple number of fins formed to the slant of the head of the rotary blade.
