SGT6-5000F (W501F) Engine Enhancements to Improve Operational Flexibility

摘要

This paper describes recent changes made to the SGT6-5000F gas turbine (previously named W501F) to enhance its operational flexibility. The engine is designed for a wide range of operating modes, such as peaking, intermediate and continuous duty. The changes incorporated will further enhance its demonstrated record in flexible operation demanded by the current US market conditions of overcapacity and high fuel prices. This paper describes benefits resulting from these changes, as well as verification testing carried out to validate them. The changes focused on engine operation, performance, component mechanical integrity and combustion system improvements. The paper also summarizes the SGT6-5000F field experience over the 15 years since its introduction and outlines planned improvements for the near future.
