Steam turbine STF 600 series

single-shaftcombined-cycle

High performance in a compact footprint. •The STF-A650 is a two-casing reheat steam turbine with a combined IP-LP section and a separate HP section. •Main steam inlet pressures up to 2,680 psi (185 bar) with main steam inlet and reheat temperatures up to 1,112°F (600°C). •Can be applied in both single-shaft and multi-shaft configurations, with the single-shaft configuration incorporating a clutch for enhanced operational flexibility. •Features fully assembled HP and IP/LP sections, enabling installation in as little as five months. •GE’s proven shrink ring design applied to the HP section reduces distortion, allowing critical clearances to be maintained and sustaining performance over the life of the machine. GE’s STF-D600 steam turbines primarily support H-class and F-class gas turbine combined-cycle plants. • The STF-D600 consists of a combined HP/IP section with either one or two dual flow LP sections. • Main steam inlet pressures up to 2,680 psi (185 bar) with main steam inlet and reheat temperatures up to 1,112°F (600°C). • Single bearing design reduces construction time, increases power density and enhances reliability by avoiding load shifts. • Available with side- or down-flow LP exhaust to provide plant layout flexibility. • HP/IP Section and valves are shipped fully assembled • Developed to deliver highly efficient power generation for single-shaft or multi-shaft plants and for sites with relatively low condenser pressure. • Self-synchronizing clutch reduces startup auxiliary steam demand, enabling industry-leading total plant startup times. • Side LP exhaust enables ground-level condenser connections and reduced plant height reducing overall plant cost.
