A method for the generation of energy in a second energy generating system comprising a gas turbine as well as power plant for carrying out the method

摘要

In the case of a process for the generation of energy in a a gas turbine (12) comprising a power plant (10), in a first step, an oxygen-containing gas in a compressor (13, 14) of the gas turbine (12) is compressed, in a second step, the compressed gas, with the addition of fuel in a combustion chamber (15) is fed to a combustion, in a third step in which the hot flue gas from the combustion chamber (15) in a turbine (16) of the gas turbine (12) is expanded while performing work, and in a fourth step, a branched-off partial stream of the expanded flue gas in an upstream of the combustion chamber (15) lying part of the gas turbine (12) and returned to the compressed.In such a method, a reduction of the co₂-Emission with minimum losses of efficiency achieved in that from the circulating gas in a co₂-Separator (19) carbon dioxide (co₂) is separated off, and that measures to compensate for the with the co₂-Separation efficiency losses, which is connected in the gas turbines - cycle are taken.
