Abstract

The feasibility of using inlet air cooling by virtue of the cold energy of liquefied natural gas (LNG) to increase power output of gas/steam combined cycle power plants during warm seasons is analyzed. Air cooling capacity and power augmentation for a combined cycle system based on a high performance gas turbine are demonstrated as a function of the ambient temperature and humidity. It is shown that the relative increase in power of the combined cycle plant amounts to 8% for dry air condition (relative humidity lower than 30%) and 6% for usual humidity conditions (60% relative humidity). The system appears feasible even with a realistic air pressure loss in the inlet air cooler if humidity is not too high.
