Casing structure of steam turbine
A steam turbine has an outer casing that is divided into an upper casing and a lower casing (a lower block) on a horizontal plane through which a rotor passes. The upper casing is divided into a middle block having a through hole and an upper block having a top panel, that is, into a portion including at least a part of the through hole through which the rotor penetrates. With this configuration, machining of a bellows fitting unit provided in an end-plate cone portion can be performed in existing facilities such as a factory, in a state that the lower block and the middle block are assembled without assembling the upper block.
