GE-Alstom Steam Turbines STF50
(设备/材料)
描述:
Alstom has offered several series and models of steam turbines for the industrial process and power generation markets for combined-cycle operation. All machines use several modules of varying sizes to produce the power and steam output required. Blades are typically made from single-piece forgings. The HP turbine shafts are also made from solid, single-piece forgings, while LP turbine shafts are composed of three forged-steel discs welded together with integrated coupling sections. Single-shell, axial symmetric cases are used for HP sections. They are split horizontally along the turbine axis and bolted together with expansion bolts. The STF50 is a three-casing reheat steam turbine with an HPT, IPT, and double-flow LPT, with a downward condenser. It has a gas/water-cooled generator for 50-Hz operation.
