ABSTRACT:
A method for operating a turbogroup, especially of a power generating plant, is provided. The turbogroup includes a compressor for compressing combustion air, a combustion chamber with at least one burner for producing a hot gas, and a turbine for expanding the hot gas, performing work. The method includes feeding combustion air to a compressor, where it is compressed, and fed to at least one burner and feeding a fuel to the at least one burner. The method also includes injecting water into the combustion air upstream of the burner where it is evaporated, mixing the fuel in the burner with the combustion air-water vapor mixture, combusting the fuel-combustion air-water vapor mixture in the combustion chamber, and feeding the hot gas which is produced in the combustion chamber to the turbine where it is expanded and performs work.
