Abstract

PURPOSE:To improve cooling performance by providing a cavity in a blade main unit being extended in its height direction and a partitioning wall in the vicinity of the central part in a chord direction of the cavity, providing communication holes in the partitioning wall, dividing the cavity by the partitioning wall into front and rear parts and providing a guide cylinder, for partitioning a gas cooling duct, to be inserted into each cavity. CONSTITUTION:In the case of a stationary blade of a gas turbine, forming a cavity in a blade main unit being extended in the direction of its height, this cavity is separated into the first and second cavities 23a, 23b by a partitioning wall 22 provided in the vicinity of the center of the blade in its chord direction in such a manner as to connect metal parts in back and belly sides of the blade. The partitioning wall 22 forms in its height direction two or more communication holes 24, connects each cavity 23a, 23b to communicate with each other. While providing guide cylinders 25a, 25b, for respectively independently guiding cooling fluid, to be inserted into each cavity 23a, 23b, thus gas cooling ducts 27a, 27b are partitioned between each guide cylinder 25a, 25b and protrusive parts 26a, 26b formed so as to extend in a chord direction in a wall internal surface of each cavity 23a, 23b.
