Back pressure or condensing turbines, where the steam path is adapted to the needs of the individual customer, provide an optimal solution when medium pressure and temperature conditions are available.
| Power output | up to 8.5 MW |
| Rotational speed | up to 7,500 rpm |
| Inlet steam pressure | up to 65 bar / 945 psi |
| Inlet steam temperature | 480 °C / 895 °F |
| Exhaust pressure | Back pressure: up to 10 bar (a) / 145 psi; Condensing: up to 1 bar / 14.5 psi |
| Exhaust area | 0.22 m² / 2.4 sq.ft. |
All data are approximate and project-related.
- Cost effective, high reliable solution
- Fast and early layout planning
- Short delivery times because of highly predefined design of both turboset and package
- Short on-site erection: turbine skid and gearbox / oil unit fully assembled in the workshop before shipping to site
- Compact design - oil system fully integrated into the base frame
- Proven components: highly standardized, robust blading; reduction gears taken from the existing range of world-class gear manufacturers
- Increased safety: no leaks towards hot pipes; oil and steam piping separated
- Easy maintenance with low maintenance costs
The single body turbine SST-100 is designed for high thermoflexibility, permitting short start-up times and rapid load changes.
- Single-casing multi-stage steam turbine
- Highly predefined proven and compact design
- Workshop assembly
- Oil system integrated in base frame
- Separation of oil and steam piping
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
