A recent energy analysis of fogging inlet cooling with over-spray showed that inlet air fogging increases the power input to the compressor, peaking when the inlet air is saturated [11]. Athariet al. [12] applied exergy analysis to biomass gasification in gas turbine power cycles, with and without fogging inlet cooling.
They revealed that inlet cooling is effective for mitigating the
decrease in gas turbine performance during hot and humid summer
periods when electrical power demands peak, and steam injection,
using steam raised from the turbine exhaust gases in a heat
recovery steam generator, is an effective technique for utilizing the
hot turbine exhaust gases. Their proposed cycle, which utilizes
bio-fuel as an energy source, have a lower total unit product cost
than a similar plant fired by natural gas.
