Gas turbine and combined-cycle capacity enhancement
This report presents interim results of a study of capacity enhancement of gas turbines and combined cycles. A portion of the study is based on a tailored collaboration study for Missouri Public Service. The techniques studied include water injection, steam injection, increased firing temperature, supercharging, and inlet cooling for the gas turbines. The inlet cooling approaches cover evaporative cooling with and without media, water cooling, thermal energy storage (TES) systems using ice or water and continuous refrigeration. Results are given for UTC FT4/GG4, GE MS5001, MS7001, W501 and W251 gas turbines. Duct firing of a three-pressure HRSG for peaking capacity is investigated. The GE PG7221(FA) is used as the reference gas turbine for this combined cycle. The results to-date indicate that the utilities have a number of viable options for capacity enhancement that are dependent on the mission of the gas turbine, local climate, and the design of the gas turbine.
