Abstract

A steam cooled gas turbine system in a combined power plant, constituted such that gas turbine blade cooling steam and combustor tail pipe cooling steam are bled from an outlet of a high pressure turbine, passed through a fuel heater for heat exchange with fuel, sprayed with water to be cooled to predetermined temperatures, and then supplied to cooling areas, whereby the cooling steam supply temperatures can be maintained at predetermined values during partial load operation as well as rated operating to achieve effective cooling.
