<p>PROBLEM TO BE SOLVED: To provide an inlet guide vane of a compressor for a gas turbine accelerating atomization of water droplets emitted from the rear edge of the inlet guide vane, and capable of suppressing erosion in a rotor vane at an initial stage.SOLUTION: An inlet guide vane 60 of a compressor for a gas turbine is disposed to a compressor 10 for a gas turbine that includes a suction duct 50, having an atomizer atomizing water droplets, on an upstream side. The inlet guide vane 60 includes a groove 90 that is formed in an air flowing direction so as to face to a rear edge 82 on at least a part of the surface of the inlet guide vane 60, guides a water film 110 due to water droplets adhering to the surface to the rear edge 82, and accelerates atomization of the water film 110 in the rear edge 82.</p> |
