摘要： A method is provided for operating a combined cycle power plant having at least one gas turbine, a heat recovery steam generator (HSRG), a steam turbine and a CO2 capture system. The method includes recirculating a first partial flow of flue gases from the HRSG. The method also includes capturing CO2 from a second partial flow of flue gases from the HRSG; and operating a supplementary firing to increase the net power output of the plant and to at least partly compensate the power consumption of the CO2 capture system. A combined cycle power plant is also provided. The plant includes at least one gas turbine, at least one heat recovery steam generator, at least one steam turbine at least one CO2 capture system, and flue gas recirculation. The plant also includes a low excess air supplementary firing.

摘要： The invention relates to a combined cycle power plant including a gas turbine the exhaust gas outlet of which is connected to a heat recovery steam generator, which is part of a water/steam cycle, whereby, for having a large power reserve and at the same time a higher design performance when operated at base load, the gas turbine is designed with a steam injection capability for power augmentation. For having a large power reserve at improved and optimized design performance when the plant is being operated at base load, the gas turbine includes at least one combustor, and a compressor for providing cooling air for that gas turbine, which is extracted from the compressor and cooled down in at least one cooling air cooler. The steam for steam injection is generated in said cooling air cooler, whereby said steam is injected into an air side inlet or outlet of said cooling air cooler and/or directly into said at least one combustor. The heat recovery steam generator is equipped with a supplementary firing, which is at least a single stage supplementary firing to increase the high pressure steam production and providing augmentation power as power reserve to a grid when required.

摘要： The invention relates to a combined cycle power plant that includes, a gas turbine plant, a heat recovery steam generator heated by hot waste gases of a gas turbine plant, and a steam turbine plant driven by the steam produced, and a waste gas purification plant, arranged downstream of the heat recovery steam generator in which carbon oxides in the waste gases can be absorbed by an absorber fluid, which is subsequently regenerated at an elevated temperature in a regenerating section while giving up the carbon oxides for supplying to a storage. The regenerating section has a heater for maintaining a necessary elevated temperature for regeneration. The heater operates with steam from the heat recovery steam generator or from the steam turbine plant. The steam condenses and the resulting hot condensate can be supplied to a flash boiler where it, at low pressure, immediately at least partially evaporates. This steam can be supplied to an appropriate stage of the steam turbine plant according to the steam pressure.
