摘要： A cooling structure of a combustor tail tube is capable of avoiding the formation of cracks in the tail tube by lessening thermal stress and preventing thermal deformation, thus extending the service life. A multiplicity of cooling jackets (5) extend in the longitudinal direction of the tail tube of a gas turbine combustor along the entire circumference of the tail tube wall. The passage sectional area of the cooling jackets (5) is varied depending on the metal temperature of parts of the tail tube (4). For example, the passage sectional area of the cooling jackets (5) formed at the rotor side wall and the mutually opposite side walls of the adjacent tail tube is larger than the passage sectional area of the cooling jackets (5) formed at the casing side wall.

摘要： In the gas turbine split ring, on an outer peripheral surface 1b between two cabin attachment flanges, a circumferential rib which extends in the circumferential direction and an axial rib which extends in the axial direction and has a height taller than that of the circumferential rib are, respectively, formed in plural lines, so that it is possible to suppress heat deformation in the axial direction which largely contributes to reduction of the tip clearance compared to head deformation in the circumferential direction more efficiently.

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.
