GE-Alstom Steam Turbines STF15S
(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 STF15S is a two-casing steam turbine with an HPT and IPT/LPT, and an axial condenser. It also has an air-cooled generator for 60-Hz operation
