Steam turbine SST-700

for power generationcombined-cycle

The SST-700 / 900 is a standard turbine solution with short delivery time due to its fixed pre-engineered design. Predefined modules enable a short manufacturing period, cost-efficient material supply and a fast ex-works delivery. The straight flow turbine solution with power output of up to 250 MW consists of a geared high-pressure steam turbine (backpressure), an intermediate / low-pressure steam turbine (condensing), both driving a generator installed in between. The dual casing reheat turbine configuration with inner casing is a competitive and optimized product for combined cycle power plants and concentrated solar power plants. •Speed 3,000 to 3,600 rpm •Inlet pressure up to 180 bar / up to 2,611 psi •Inlet temperature up to 585 °C / up to 1,085 ° F •Exhaust steam parameters: up to 0.3 bar / 4.4 psi •Reheat steam temperature: 565°C / 1,050°F •Reheat steam pressure: 45 bar(a) / 842 psi •Controlled extractions: 72 bar / 1,044 psi •Uncontrolled extractions (up to 7): uncontrolled extractions possible Combined cycle power plants Concentrated solar-thermal power plants Biomass-fired power plants
