In a gas turbine, having a number of turbine blades/vanes respectively combined to form blade/vane rows, each of the turbine blades/vanes including an integrated cooling air duct, the cooling air requirement is to be kept particularly low in conjunction with reliable cooling of the turbine blades/vanes. For this purpose, the turbine blades/vanes forming a first turbine blade/vane row and the turbine blades/vanes forming a second blade/vane row connected downstream thereof, viewed in the flow direction of the working medium, are connected one behind the other on the cooling air side with the intermediate connection of an injection device for water. During the operation of the gas turbine, the cooling air flowing out of the turbine blades/vanes forming the first blade/vane row is intercooled by the injection of water and is subsequently supplied to the cooling air ducts of the turbine blades/vanes forming the second blade/vane row.
