Powerful and reliable – thanks to proven design for high efficiency

The SST-4000 series is our specialized turbine forÌýnon-reheat, combined cycle applications. With theÌýspecialized design of the blade path, the entireÌýpower range from 100 to 500 MW can be coveredÌýwith the highest reliability and availability. MoreÌýthan 40 turbines of this type are already in operation or in the commissioning stage, with a totalÌýinstalled capacity of approximately 8,200 MW.

The SST-4000 series consists of an intermediate-pressure and a low-pressure turbine. TheÌýinstallation is either high or low level arrangementÌýwith down, double-side or single-side exhaust.ÌýThe turbine is able to provide process steamÌýe. g. for industries or sea water desalination andÌýcan provide industrial heating.

Thanks to its systematically modular design, theÌýSST-4000 series can easily be adapted to the individual operating conditions and thermal cycleÌýdesign of the plant. Its fast installation, thanks toÌýprefabricated, tested modules delivered ready forÌýconnection, is of additional advantage.

A steam turbine with short start-up times and variable start-up modes to ensure grid stability

µÂÖÝÆË¿ËÔÚÏß Steam Turbines of the SST-5000Ìýseries are operated in combined cycle powerÌýplants (CCPP) and in steam power plants (SPP).Ìý

The SST-5000 steam turbine combined with aÌýgas turbine, is able to achieve a net plant efficiency of more than 64 percent in combined cycle applications.

Reduced life-cycle costs

µÂÖÝÆË¿ËÔÚÏß Steam Turbines of the SST-6000 series are widely operated in 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.

Leading technology for efficient, flexible and reliable power generation

µÂÖÝÆË¿ËÔÚÏß Steam Turbines of the SST-9000Ìýseries are highly reliable for the application in conventional islands ofÌýadvanced pressurized water reactors in nuclearÌýpower plants, with a power output up toÌý1,900 MW.

The half-speed (25 turns per second) SST-9000 series consists of a double-flow high-pressure saturated steam turbine (HD) and up to three twin-flow low-pressure turbines (ND) with shrunk-on wheel disc rotors. µÂÖÝÆË¿ËÔÚÏß low-pressure turbines with shrunk-on wheel discs represent technology that has been proven over decades. The result: no stress corrosion cracking and thus no replacement of the low-pressure rotor or wheel discs during the excepted service life.
