Abstract: A method for operating a power plant (2), which includes at least one compressor (3), at least one turbine (4), and a burner arrangement (5), involves, to enhance the power plant (2), feeding a combustion exhaust gas from a pre-burner (8) of the burner arrangement (5) to an oxygen-removal device (11), which removes gas of the oxygen from the combustion exhaust gas in which it is contained.

Abstract: A thermal power plant with sequential combustion and reduced CO2 emissions is disclosed, which includes the following components, which are connected in series via in each case at least one flow passage (S): a combustion feed air compressor unit, a first combustion chamber, a high-pressure turbine stage, a second combustion chamber and a low-pressure turbine stage. The second combustion chamber and/or the low-pressure turbine stage can be supplied with a cooling gas stream for cooling purposes. A method for operating a thermal power plant of this type is also disclosed.

Abstract: In a method for generating energy in an energy generating installation (10) having a gas turbine (12), in a first step, an oxygen-containing gas is compressed in a compressor (13, 14) of the gas turbine (12), in a second step the compressed gas is supplied, with the addition of fuel, for combustion in a combustion chamber (15), in a third step the hot flue gas from the combustion chamber (15) is expanded in a turbine (16) of the gas turbine (12) so as to perform work, and, in a fourth step, a branched-off part stream of the expanded flue gas is recirculated into a part of the gas turbine (12) lying upstream of the combustion chamber (15) and is compressed. A reduction in the CO2 emission, along with minimal losses of efficiency, is achieved in that carbon dioxide (CO2) is separated from the circulating gas in a CO2 separator (19), and in that measures are taken to compensate for the efficiency losses in the gas turbine cyclic process which are associated with the CO2 separation.
