摘要： A method is provided for CO2 separation from a combined-cycle power plant with exhaust-gas recirculation and CO2 separation. The hot-gas flow is split into a recirculation flow and an exhaust-gas flow before the final turbine stage in the turbine. A first partial flow remains in the turbine and carries out expansion work in the conventional form, before its waste heat is dissipated, for example in a waste-heat boiler, and the gases are recirculated into the inlet flow of the gas turbine. A second partial flow is diverted before the final turbine stage, and emits its waste heat in an HRSG/heat exchanger, before CO2 is separated from the exhaust-gas flow at an increased pressure level.

摘要： A method is provided for operating a power station (10) with turbine shafting (11) including a gas turbine (12) and a generator (18) that is driven directly by the gas turbine (12) and that generates alternating current with an operating frequency. The output of the generator is connected to an electrical grid (21) with a given grid frequency. An electronic decoupling apparatus or variable electronic gearbox (27) is arranged between the generator (18) and the grid (21). The decoupling apparatus decouples the operating frequency from the grid frequency. In the event of a temporary over-frequency or under-frequency event in the electrical grid (21), the mechanical rotational speed of the gas turbine (12) is decreased more than the grid frequency during an under-frequency event of the electrical grid (21) and is increased more than the grid frequency during an over-frequency event of the electrical grid (21).

摘要： An exemplary system method for the operation of a CCP P with flue gas recirculation to reduce NOx emissions and/or to increase the CO2 concentration in the flue gases to facilitate CO2 capture from the flue gases is disclosed. The flue gas recirculation rate (rFRG) is controlled as function of the combustion pressure and/or the hot gas temperature.

摘要： A gas turbine and method are disclosed by which the gas turbine can be safely operated at nominal speed with reduced margin to a surge limit of a compressor. The gas turbine, via a directly driven generator which generates alternating current with an operating frequency and which is connected in a frequency-coupled manner to an electricity grid, can deliver electric power to this grid. In the case of an underfrequency event the compressor of the gas turbine is unloaded by controlled, fast closing of the variable compressor guide vanes (VGV) and as a result maintains a sufficient margin to the surge limit of the compressor.
