Steam turbine STF-D1050

for power generation

The STF-A1050 and STF-D1050 steam turbine family expands the range of ultra-supercritical (USC) steam turbines from 150 MW to over 1,200 MW. Its cycle efficiency of up to 50% and operating flexibility improves economics and shortens payback for customers. Configuration flexibility The fully modular architecture facilitates configuration of reheat steam turbines for even the most demanding applications. Options include multiple controlled extractions, overload valves, and a wide range of LP configurations. Consistent product quality GE’s extensive knowledge base and experience, combined with rigorously standardized engineering, design and manufacturing processes allow extensive customizing for any application without compromising on quality, lead time, or operating reliability. Optimized cold end for best performance and cost GE’s extensive portfolio of modern last stages ranges from 34” to 50” and allows configuration of exhaust areas between 6.5m2 and a massive 72m2. All rear stages feature GE’s proven nub-and-sleeve damping system, which ensures superior damping behavior at any flow condition. A high-performance reheat steam turbine platform designed to enhance the economics and flexibility of USC boiler plant applications in either 50 or 60 Hz grids. • Robust and versatile reheat turbines with a successful track record spanning more than 20 years. • Outstanding configuration flexibility including a wide range of HP and IP module sizes and multiple LP configurations from a single flow to three double flow LP modules as well as internally or externally controlled steam extractions for steam export.
