GE’s STF-A200 non-reheat platform
GE’s STF-A200 non-reheat platform provides cogeneration of power steam in an flexible and compact design for either 50 or 60 Hz applications, from 100 MW to 300 MW. Our fully modular concept combines HP, IP, and LP sections to deliver high efficiency and process steam supply. Available with a single casing, STF-A200 steam turbines have internally and externally controlled flow extractions to tap steam at any point along the steam path at the desired flow and pressure conditions. Arrangement options are available with axial exhausts.
The STF-A200 turbine is designed for main steam inlet conditions up to 565°C (1049°F) and 140 bar (2031 psi).
For added flexibility, the STF-A200 steam turbine is available as a single casing solution with a single flow LP section or as double casing solution with a two-flow LP section.
Turbine cylinders are shipped fully assembled to reduce site work and construction time.
An extensive LP blades portfolio allows a customized rear stage selection to fit all ambient conditions and achieve higher efficiency steam cycles.
A flexible arrangement of steam extraction nozzles along the blade path helps extract steam for project specific conditions.
Design solutions for internally controlled steam extractions are available. Adaptive stage technology is used to control low pressure steam extractions, while intersections with dedicated valves are appropriate for higher pressures
