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.
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.
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.
Specifications shown are for 50 Hz and 60 Hz.
