PROBLEM TO BE SOLVED: To suppress generation of drain in a humidification device installed between a compressor and a regenerative heat exchanger to increase a heat recovery amount in a regenerative cycle-type gas turbine including the regenerative heat exchanger.SOLUTION: A humidification device for supplying moisture to the air compressed by a compressor, includes an enlarging portion for enlarging a cross-sectional area toward the flowing direction of the compressed air, a liquid droplet spray device for spraying liquid droplets, a spray portion evaporating the sprayed liquid droplets, and a drain recovery hole for recovering drain generated in the spray portion. A rectifier is disposed at a downstream side of the enlarging portion and an upstream side of the spray device in a state of covering the entire flow channel to rectify the flow to the main flowing direction. |
