Peaking Gas Turbine Capacity Enhancement Using Ice Storage for Compressor Inlet Air Cooling

Abstract

Combustion turbine peaking units provide power for short time periods when hot, humid weather creates summer demand peaks. These same weather conditions degrade combustion turbine capacity and heat rate. Cooling combustion turbine inlet air increases its density and improves combustion turbine performance. A full size retrofit air chilling system for a G.E. MS7001B engine was installed by Lincoln Electric System, in Lincoln, Nebraska (U.S.A.), in an EPRI and American Public Power Associated supported and co-funded demonstration project. Detailed design and construction documents for the project were developed by Burns & McDonnell Engineering Company.
