Solar heat assist gas turbine system

The purpose of the present invention is to significantly reduce the number of the heat collecting apparatus is to provide a solar heat assist gas turbine system by reducing the site area required for installation of the heat collector device. The present invention includes a compressor 1 for compressing air, a combustor 3 for burning a fuel air compressed by the compressor, the turbine 2 driven by the combustion gas generated in said combustor a gas turbine apparatus 100, and the heat collecting device 200 to generate a high-pressure hot water heated collecting solar heat, and the heat storage tank 57 for storing the heated medium of After the temperature rise, said the heated medium and water and heat exchange hot water a heat exchanger 24 for generating, characterized in that a spraying device 300 for spraying hot water generated in the heat exchanger to the air taken into the compressor.
