Abstract (en)
A steam turbine assembly (1) comprises an inner casing (3) arranged around a longitudinal rotor axis (4) and a guide blade carrier or stationary blade ring (5) arranged in said inner casing circumferentially around said rotor axis. The guide blade carrier or stationary blade ring comprises a radially outward arm (10) supported between a pair of transversely separated support faces (11a,11b) of said inner casing. The assembly further includes a pair of tapered keys (13a,13b) slidably fitted respectively between said arm and each of said support faces, for transversely fastening said guide blade carrier or stationary blade ring to said inner casing.
