A New 150-MW High-Efficiency Heavy-Duty Combustion Turbine

Abstract

The 501F 60-Hz Combustion Turbine has been developed jointly by Westinghouse Electric Corporation and Mitsubishi Heavy Industries, Ltd. It continues a long line of large heavy-duty single-shaft combustion turbines by combining the proven efficient and reliable concepts of the W501D5 with the low NOx technology of the MW701D, together with the experience of the advanced cooled MF111. The new engine is described along with the improved evolutionary changes made from previous engines. Planned design and performance verification programs including model, full-scale component testing, and full-load engine tests are described. Mature output and efficiency in simple cycle mode will be 145 MW and 34 percent, respectively, with expected combined cycle efficiencies in excess of 50 percent.
