Westinghouse 501B Heavy-Duty Gas Turbine — 75–80 MW (W501B)
Westinghouse 501B (W501B) 60 Hz heavy-duty gas turbine for sale — the 75–80 MW-class predecessor of the 501D, used in simple- and combined-cycle plants.
Westinghouse 501B heavy-duty gas turbine available through Pantheon. First started in 1973, the W501B is a 75–80 MW-class, 60 Hz single-shaft frame at 3,600 rpm: 17 compressor and 4 turbine stages, an 11.2:1 pressure ratio, 746 lb/s airflow and about 907 °F exhaust, at a simple-cycle heat rate of 11,180 Btu/kWh (7,350 Btu/kWh in combined cycle). It sits between the 60 MW W501AA and the 95 MW W501D in the 501 line that led to the 501D5 and today’s Siemens SGT6-5000F. B2 through B6 variants remain in service and are supported by independent service providers. Exact rating, variant, and configuration confirmed at quote.
