Abstract

PURPOSE: To reduce steam leakage so as to improve the efficiency of a turbine, by arranging pieces of a shroud plate cut in halves in butt joint form on the top edge of a plural number of rotary blade implanted along the periphery of a rotor and also allowing fins to protrude from the both sides of the pieces of the shroud plate cut in halves.
CONSTITUTION: A steam turbine is provided with a turbine rotor 1 including impellers 2 as its integrated portions, where a plural number of rotary blade 10 are implanted on each impeller 2 and also provided with a nozzle plate 21 which is installed upstream in relation to the above rotor 1 and enclosed with its own somma ring 20, 22 in the nozzle space, and whole nozzle plate unit 21 is surrounded by a casing 50. Then, pieces 11a, 11b of a shroud plate cut in halves are set on the top edge of a rotary blade 10 and fixed to it by caulking tenons 12a, 12b integrated to the rotary blade 10. Fins 30a, 30b and 31a, 31b are formed on each of shroud plate 11a, 11b respectively, and tip fing 24a, 24b are formed on somma ring 22 of the nozzle so that they may be positioned at the centers of fins 30a, 30b and 31a, 31b respectively.
