Abstract

PURPOSE: To prevent a shroud from being eroded due to direct steam jet by putting anti-erosion shields between a blade and a shroud to build up a lamination.
CONSTITUTION: A hole 4 to be keyed with a projection 2 on a blade 1 is made through two thin strips of shields 8, 9 made of anti-erosive material. A similar hole is made in a shroud 6, which is put on the shields 8, 9 and the projection 2 of the blade 1 is caulked to fix them on. Each edge of the shields 8, 9 is bent to make a fin 5. The anti-erosive shields 8, 9 are exposed to steam jet to prevent erosion of the shroud. The fins 5 at the ends of the shields 8, 9 function to seal.
