Reheat steam turbine STF-D650

combined-cycle

GE Vernova’s STF-D650 combined-cycle steam turbine delivers the reliability and availability needed in today’s demanding energy environment. The STF-D650 turbine consists of separate HP, IP, and a two flow LP Section. Single bearing design reduces construction time, increases power density and enhances reliability by avoiding load shifts. HP, IP, and valves are shipped fully assembled. Self-synchronizing clutch reduces startup auxiliary steam demand, enabling the gas turbine to reach 85 percent load in less than 20 minutes under hot start conditions. Available with side- or down-flow LP exhaust provides plant layout flexibility. Side LP exhaust enables ground-level condenser connections and reduced plant height reducing overall plant cost. The STF-D650 HP section uses GE Vernova’s proven shrink ring design reducing distortion, allowing critical clearances to be maintained and sustaining performance over the life of the machine.
