Siemens Steam Turbines

Siemens has a comprehensive range of steam turbines for the power output range up to 12 MW which stand out distinctly from the products of other suppliers in that its machines are built according to the modular principle. Because of the many different possible combinations of individual modules, these compact steam turbines can be adapted flexibly to the specific requirements of the individual operator.

As global market leader for industrial steam turbines, we offer a comprehensive range of reliable and versatile steam turbines for the power output range from 2 to 250 MW. Our industrial steam turbines up to 250 MW are designed for fast start-up and economical operation.

Siemens offers a comprehensive range of steam turbines for the 50 Hz and 60 Hz market in the power output range from 90 to 1,900 MW. These are used in steam power plants as well as in combined cycle power plants. With more than 8,000 steam turbines in service worldwide we provide proven technology, adapted to the specific local conditions.

Steam turbines play a significant role in combined cylce and steam power plants and in many industrial applications, not least in the oil and gas, pulp and paper, food and beverage and metal industries. The renewable energy sector, such as biomass, waste-to-energy, seawater desalination and applications for solarthermal energy, are also major users of steam turbines.

Siemens delivers the first oil-free steam turbine and successfully commissions it in the Vattenfall Jänschwalde power plant in early 2015. In contrast to a conventional rotor supported by an oil film, the link between the rotor and bearing in an oil-free turbine is in the form of an active magnetic bearing. The rotor is literally floating. The valve actuators are nearly oil-free and are controlled by electric motors. The only quantity of oil required for operation of the steam turbine is thus less than 10 liters.
