GE Power Systems and Toshiba have developed new 40-inch and 48-inch steel last-stage buckets for steam turbine applications worldwide. The new buckets are designed for both 50 and 60-Hertz applications to increase steam turbine power output capability and improve efficiency. The 48-inch last-stage bucket is the largest 3000-rpm last-stage bucket in the world in terms of annulus area. GE and Toshiba expect to offer the new buckets on their steam turbines for both combined-cycle and fossil power plant applications shipping in 2003.
