Siemens Steam Turbines of the SST-6000 series are widely operated in coal-fired steam power plants with a power output up to 1,200 MW and an efficiency up to more than 46 percent.
Products of the SST-6000 series consist of a high-pressure turbine, an intermediate-pressure (IP) turbine, and up to three low-pressure turbines for 50 and 60 Hz.
The SST-6000 is installed as a high-level arrangement with down exhaust. Various extractions (up to 10 stages) are possible for feed water preheating, process steam, and district heating. The installed capacity of SST-6000 all over the world is more than 100,000 MW.
