This paper describes the value of direct spray inlet cooling in gas turbine cycles. A series of centrifugal compressor performance tests are shown. And simple cycle gas turbine and recuperated gas turbine performance analyses are also shown. The results show that the direct spray inlet cooling in gas turbine cycle gives sufficient power augmentation and improvement of fuel consumption ratio because compressor work is reduced by the effect of "Wet Compression" nevertheless the cooling system is simple and easily retrofitted. Significant surge line change, vibration and other negative symptoms are not detected by high fogging itself as long as fog droplets are fine enough.
