Influence of atmospheric air conditions and inlet air cooling systems on gas turbine performance.

Summary

This article shows the influence of atmospheric air conditions in gas turbine thermodynamic efficiency, and the benefits with the utilization of inlet air cooling systems. A comparison has been made between two cooling technologies: evaporative cooling and absorption systems driven by turbine effluent gases. The four configurations considered in this study were: gas turbine without inlet air cooling, gas turbine with evaporative cooling, gas turbine with absorption cooling system that uses steam generated in a heat recovery boiler and gas turbine with absorption cooling system directly driven turbine effluent gases. The performance of each configuration was analyzed using a mathematical simulation model developed in this work. The inlet air cooling increases the power generated in the range of 2 to 3 % for evaporative cooling, 8 to 13 % for absorption system driven by water steam and 12 to 18 % for absorption system driven directly by exhaust gases.
