Project Description
NETL is partnering with General Electric Company to develop a high-performance, heavy-duty gas turbine wheel that could increase combined cycle turbine efficiency from approximately 62 to 65%. Specifically, the project will screen two different concepts to develop a thick section >1,200 °F-capable material for heavy-duty gas turbine wheels. The processing requirements for these large components, combined with the elevated temperature and stress property requirements, present a unique set of challenges requiring a new approach to alloy design that will be addressed in this project.
Project Benefits
This project, if successful, will increase gas turbine efficiency, which directly translates to a decrease in fuel consumption (4-7%) and reduced capital costs from higher output. A reduction of 3 to 6% in the CO2 produced per MW of power generated may also be realized.
