Steam turbine SST-200

for power generationreaction

The SST-200 is a single casing steam turbine provided in a packaged, skid-mounted configuration. It represents a solution based on long experience with both mechanical and generator drives and is characterized by ease of installation, facilitated by the modular package. The tailor-made, flexible steam turbine exactly fits to the customer needs. The Siemens SST-200 industrial steam turbine product line is based on the reaction blade technology. The turbine series follows a modular product philosophy, ensuring a high level of performance and reliability. The ability to combine standardized casing modules enable optimal design flexibility. This allows the turbine series to achieve high performance in combination with an optimal cost position. •A high degree of standardization and lean specifications reduce the time to take the steam turbine in operation and provide easy maintenance. The combination of these factors lead Siemens to deliver a highly reliable products, with the short delivery times that suit this market segment. •Implementation of the latest blading technology has led to efficiency improvements of up to 2% compared to previous turbine design. •Optimal total cost ownership due to standardized components, highest efficiency, and optimized maintenance concept. •Inlet steam pressure: up to 120 bar (a) / 1,740 psi •Inlet steam temperature: up to 540º C / 1,004° F •Exhaust conditions: Water-cooled condenser: 0.05–0.15 bar (a) Air-cooled condenser: 0.15–0.50 bar (a) Backpressure turbines: 2–20 bar (a) Uncontrolled extraction: 60 bar / 870 psi (up to 3) Controlled extraction: 16 bar / 230 psi
