Westinghouse is now offering its latest upgrade of the 501D5 family of combustion turbines. This upgrade engine, designated 501D5A, is based on recent technical advancements successfully incorporated in the 251B12 and 701DA engines. These advancements primarily focus on compressor end modifications for increased mass flow and turbine end modifications for a modest increase in rotor inlet temperature. In addition, modifications were made to the combustion section for use of low emissions combustion systems. This paper will describe these changes incorporated in the upgraded 501D5, along with improvements associated with engine efficiency, which have resulted in an engine with over 10 percent increased power and over 2 percent improved simple cycle heat rate.
