PERFORMANCE AND RELIABILITY IMPROVEMENTS FOR HEAVY DUTY GAS TURBINES.

Abstract

Many signficant advances in technology have been applied to new unit production in the past 15 years. These technology improvements can be applied to field units to achieve increased performance, life, and/or reliability. Several types of improvement are now available for compressors, combustion systems, hot gas path turbine parts, and turbine controls. This paper provides a summary of performance improvements available for General Electric gas turbines MS3002, MS5001, MS5002, MS6001, MS7001, and MS9001 and tabulations of performance for each improvement. Also provided are detailed descriptions of control modernization designs available for improving the operating reliability of field units.
