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.

What is claimed is: 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. 2. The method as in claim 1, wherein a hydrocarbon-free combustible gas which contains hydrogen gas is used as fuel, or a dry, evaporated liquid fuel, for example dehydrated oil, is used as fuel, or hydrogen gas is used as fuel. 3. The method as in claim 2, wherein water is injected into the combustion air in such measure that a dilution of about ten percent by volume is produced for the fuel in the burner. 4. The method as in claim 2, wherein the water is injected into the combustion air inside the compressor. 5. The method as in claim 2, wherein the water is injected into the combustion air upstream of the compressor or in a compressor inlet section. 6. The method as in claim 1, wherein water is injected into the combustion air in such measure that a dilution of about ten percent by volume is produced for the fuel in the burner. 7. The method as in claim 1, wherein the water is injected into the combustion air inside the compressor. 8. The method as in claim 7, wherein the water is injected into the combustion air in an intermediate-pressure section of the compressor, or in a low-pressure section of the compressor, or the water is injected into the combustion air between an intermediate-pressure section of the compressor and a high-pressure section of the compressor, or between a low-pressure section of the compressor and an intermediate-pressure section of the compressor, or between a low-pressure section of the compressor and a high-pressure section of the compressor. 9. The method as in claim 1, wherein the water is injected into the combustion air upstream of the compressor or in a compressor inlet section. 10. The method as in claim 1, wherein the water is injected into the combustion air by an inlet atomizing device, which produces water vapor at or in a compressor inlet section. 11. The method as in claim 1, wherein the water is injected into the combustion air by a compressor intercooling device, which injects water into the compressor between two pressure stages of the compressor or between two pressure sections of the compressor. 12. The method as in claim 1, wherein a hydrocarbon-free combustible gas which contains hydrogen gas is used as fuel, or a dry, evaporated liquid fuel, for example dehydrated oil, is used as fuel, or hydrogen gas is used as fuel. 13. The method as in claim 1, wherein water is injected into the combustion air in such measure that a dilution of about ten percent by volume is produced for the fuel in the burner. 14. The method as in claim 1, wherein the water is injected into the combustion air inside the compressor. 15. The method as in claim 1, wherein the water is injected into the combustion air upstream of the compressor or in a compressor inlet section. 16. The method as in claim 1, wherein the water is injected into the combustion air by an inlet atomizing device, which produces water vapor at or in a compressor inlet section.
