Abstract:
1. A method for operating a turbogroup, which at least comprises 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 comprising: feeding combustion air to a compressor, where it is compressed, and fed to at least one burner, feeding a fuel, having a higher combustion reactivity than natural gas, to the at least one burner, 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, wherein the water is injected in such measure that the vapor portion in the combustion air-water vapor mixture is about five to eight percent by mass.
