Abstract

1336384 Steam turbines GENERAL ELECTRIC CO 14 July 1971 [10 Sept 1970] 32919/71 Heading FIT The inner casing 21 of a double casing steam turbine defines an interstage steam extraction passage 24 leading to pipes 25 and is divided into upper and lower sections 21a, 21b connected by bolts 28 at a horizontal joint 26 disposed at a distance substantially above the rotor axis. The distance may be between “ and ¢ the radius of casing 21. Sealing keys (29) Fig. 3 (not shown) may be disposed at joint 26. Bladed diaphragms 12 having lugs 13 are supported on pads 27 level with the rotor axis, the pads being secured to radial casing walls 23. Lugs 13 are held in position by square headed pins 30. The outer casing 1 is divided into sections joined at 2 level with the rotor axis and is supported on foundation 3.
