Steam Turbine SST-800 (up to 150 MW)
- Description
- Technical Data
- Benefits
- Design Concept
- Package
The SST-800 steam turbine is a single-casing direct drive with reverse flow design, used for tailor-made applications for the most complex processes in industry and power generation. It operates at 3,000 or 3,600 rpm for generator drives up to 150 MW and at variable speed up to 5,000 rpm for compressor drives. The turbine can be used for both condensing and back-pressure applications.
The SST-800 is proven as a compressor or generator drive in:
- Power plants – pure power production
- Combined cycle plants
- Industrial CHP (Combined Heat and Power), e.g. chemical industry, food industry, pulp and paper mills
- Petrochemical industry
- Seawater desalination plants
| Power output | up to 150 MW |
| Inlet steam pressure | up to 140 bar / 2,030 psi |
| Inlet steam temperature | up to 540 °C / 1,005 °F |
| Rotational speed | 3,000 to 3,600 rpm |
| Bleeds | up to 6, at various pressure levels |
| Controlled extraction (single or double) | pressure: up to 45 bar (a) / 655 psi |
| Exhaust area | 1.1 - 5.6 m² |
All data are approximate and project-related.
- Variable layout
- Highly customized, wide application range
- High reliability, availability and efficiency
- Easy installation and maintenance
- Compact plant layout
- Single casing
- Modular, flexible and proven design
- Reverse steam flow
- Customized steam path
- Axial or radial exhaust
Although the typical arrangements are standardized, the turboset can be configured to meet any project-specific requirements. For ground-level installation the turbine is equipped with axial or upward exhaust, yielding substantial savings in foundation and building cost. Where space is restrictive, an arrangement with downward exhaust and underslung condenser can be selected.
