ABSTRACT:
A gas turbine system comprises a compressor for compressing air, a combustor for burning the air compressed by the compressor and fuel, a turbine driven by combustion gases produced from the combustor, and a spraying apparatus for adding water to working air at least upstream or in an intermediate stage of the compressor. A rotationally symmetric groove or projection is formed in an inner wall surface defining a channel through which the working air added with the water flows, or in a channel-defining surface of a rotor or a casing of the gas turbine. A larger amount of water can be supplied to the compressor while improving the reliability of the gas turbine.
