The STF-A650 and STF-D650 reheat steam turbines offer outstanding competitive performance for high parameter renewable steam power and combined cycle applications, using GE’s latest generation of 3D reaction blading, advanced rear stages, and high-performance gland and inter-stage sealing technology.
The fully modular architecture allows configuring the steam turbines for even the most demanding applications. Options include multiple controlled extractions, and condensing, district heating or back pressure type exhausts. Modules from other product families may be used as required.
STF-A650 and STF-D650 steam turbine modules are largely factory assembled and pre-tested to save installation time. The design with an optional side exhaust configuration is optimized for low level arrangement and outdoor installation, which helps reducing total installed cost.
A versatile platform optimized for high parameter concentrated solar power applications as well as for advanced combined cycle steam tails and high efficiency industrial co-generation application in either 50 or 60 Hz grids.
Specifications shown are for 50 Hz and 60 Hz.
