STEAM TURBINE EQUIPMENT

WIPO Patent Application WO/2010/018774

A1

Provided is steam turbine equipment that enables the turbine equipment to be increased in size while inhibiting the possibility of vibration generation and a significant increase in equipment cost even when the steam temperature adopted is 650°C or higher. In a piece of steam turbine equipment having a high-pressure turbine, an intermediate-pressure turbine, and a low-pressure turbine, the intermediate-pressure turbine is separated into a first intermediate-pressure turbine unit on the high-temperature, high-pressure side and a second intermediate-pressure turbine unit on the low-temperature, low-pressure side; an Ni-based alloy forms at least one of the rotors or the entire casing of the turbine on the steam inlet side, into which steam at 650°C or higher is introduced; and at least one entire turbine rotor or the entire casing is configured by joining rotor members or casing members of multiple materials by welding.
