摘要： Precision cast hollow stationary blade used for final stage of steam turbine is improved to enhance drain recovery efficiency. Hollows (4, 5), sectioned by rib (6) to be independent of each other, are formed in stationary blade (1) passing therethrough from outer shroud 2 to inner shroud 3. A plurality of ventral slits (10 to 20) are provided on blade surface ventral side linearly with predetermined interval between the slits in two parallel rows. Dorsal slits (21 to 26) are also provided linearly with predetermined interval between the slits. Drain on blade surface enters the hollows (5, 4) through the ventral slits (10 to 20) and the dorsal slits (21 to 26), respectively, and flows out of the outer shroud (2) or the inner shroud (3) as drain (40 to 43) to be recovered. While prior art hollow is single hollow and drain entering the hollow through the dorsal slits flows out through the ventral slits or reverse case thereof occurs, the hollows (4, 5) of the present invention being sectioned by the rib (6), the drain is prevented from flowing out to the opposite side.

摘要： A two stage jointed stationary blade of a high pressure or intermediate pressure steam turbine is formed with a bolt joint in place of a welded joint so as to make detachment and disassembly possible, and thereby facilitating maintenance and inspection work and reducing assembling man-hours. A stationary blade (front stage)(2), outer ring front portion (1) and inner ring front portion (3) are welded into an integral structure. A stationary blade (rear stage) 22, outer ring rear portion (21) and inner ring rear portion (23) are also welded into an integral structure. The outer ring front portion 1, outer ring center portion 10 and the outer ring rear portion 21 are mutually engaged via engaging portions (4, 11 and 12, 24) with precise positioning and then jointed together integrally by bolt (30). The two stage jointed stationary blade can be engaged with moving blades (33, 35), labyrinth seals (32, 34) can be fitted to seal fitting portions (6, 26), and seal fins (31, 34) can be fitted in seal fin grooves (13, 27).
