Abstract
A cooling passage in a turbine blade of gas turbine can be prevented from being blocked by a scale when the turbine blade is cooled by steam. A system for cooling a blade of a gas turbine having a compressor, a combustor and a turbine section comprises a cooling steam supply tube and a steam discharge tube providing communication with a cooling passage in a guide blade of the turbine section, and a cyclone separator provided in the middle of the steam supply tube in proximity to the guide blade.
