This paper presents a review of recent developments that were made to improve the reliability and maintenance costs associated with operation of the AEC CAES plant in McIntosh, Alabama. The combustor, fuel injector, and igniter of the LP expander were redesigned by Power Tech Associates, Inc., (PTA) of Media, Pennsylvania to improve durability, facilitate maintenance as required, and reduce cost. The modified combustor system was fitted with special instrumentation, installed and tested through an in-situ development program. Test data shows significant improvement in liner metal temperatures, transition gas temperature profile and pattern factor. Combustor system dynamics and emissions were maintained at acceptable levels.
