Advanced UltraSuperCritical Steam Boiler / Turbine Program

A new 5 year effort to focus on identified candidate alloys to meet 760C and 5,000 psi operating conditions in steam turbine applications was initiated. This project augments the $50Million U.S. Department of Energy/Ohio Coal Development Office program already underway investigating boiler materials and will conduct more detailed evaluations of the weldability, mechanical properties and reparability of selected candidate alloys for rotors, casings and valves and perform scale up studies to establish a design basis for commercial scale components. Efforts associated with high nickel alloys will be targeted for developing the specific means of casting and fabricating using electric arc/AOD; vacuum and/or pressure casting and/or powder metallurgy processes. A supplemental program funded by the Ohio Coal Development Office will undertake supporting tasks such as testing and trials to define specific metal casting techniques needed for producing commercial scale components at Ohio foundries.
