The single body turbine SST-100 is designed for high thermoflexibility, permitting short start-up times and rapid load changes.
The SST-100 in back pressure application
- Steam-driven emergency stop valve
- Double-seated control valves with hydraulic actuator
- Up to six impulse stages
- The rotor is made of solid forging or with forged discs shrink-mounted on the turbine shaft and keyed. It is short and rigid, resulting in operation well below first critical speed, using babbitt-lined sliding type bearings to assure a smooth and well-damped operation.
- Exhaust flange on side, bottom half of the casing
The SST-100 in condensing application
The condensing turbine design is derived from the back pressure version. However, there are some design differences, for example:
- Up to seven impulse stages, including condensing stages
- Exhaust casing is oriented downwards through the base frame or upwards, depending on the application
- Diaphragm carrier for the last three stages
