Steam turbine SST-4000

for power generation

Powerful and reliable – thanks to proven design for high efficiency The SST-4000 series is our specialized turbine for non-reheat, combined cycle applications. With the specialized design of the blade path, the entire power range from 100 to 500 MW can be covered with the highest reliability and availability. More than 40 turbines of this type are already in operation or in the commissioning stage, with a total installed capacity of approximately 8,200 MW. The SST-4000 series consists of an intermediate-pressure and a low-pressure turbine. The installation is either high or low level arrangement with down, double-side or single-side exhaust. The turbine is able to provide process steam e. g. for industries or sea water desalination and can provide industrial heating. Thanks to its systematically modular design, the SST-4000 series can easily be adapted to the individual operating conditions and thermal cycle design of the plant. Its fast installation, thanks to prefabricated, tested modules delivered ready for connection, is of additional advantage.
