• This paper describes a gas turbine inlet air cooling system using high pressure spray nozzle. Scale model inlet duct is manufactured within water spray of inlet fogging system, and many testing was conducted on the condition of same level of actual velocity with inlet duct at site. As testing results, droplet size finally reduce to SMD 80μm at 1st blade leading edge. Next, water spray adjusting actual attack to blade is provided to test piece of same material with actual compressor blade, and weigh is measured at every constant time period for getting averaged erosion depth. As a result, it is concluded that erosion at leading edge of 1st compressor blade is predicted to be approx 1.2mm at maximum per 10 years less than acceptable limit of depth, and it may have no need for maintenance of blade replacement and so on in 10 years.
