摘要： Since CO2 is identified as a main greenhouse gas, its capture and storage is essential to control global warming. Increased competitiveness of power plants designed for CO2 capture and compression, retrofit ready power plants including efficient ways to retrofit power plants to CO2 capture plants will allow earlier utilization of CO2 capture systems (12). The objective of the present invention is to provide a fossil fired power plant (1, 2) with increased operational flexibility, which allows operation with high efficiency when a steam is extracted for the operation of a CO2 capture system (12) as well as when the CO2 capture system (12) is not operating and no steam is extracted. Further, a method to operate this kind of plant (1, 2) is an objective of the invention. An additional objective is to provide a power plant, (1, 2) which is prepared for future retrofit of a CO2 capture system (12) and is already provided with a steam cycle capable of operation with high efficiency with or without steam extraction. One main aspect of the invention is to provide a water steam cycle with two steam turbine arrangements (14, 15), one for continuous operation independent of CO2 capture operation, and one which can at least partially be shut down during CO2 capture operation.

摘要： Since CO2 is identified as a main greenhouse gas, its capture and storage is essential to control global warming. Flexible, optimized operation of CCPPs (combined cycle power plants) with a CO2 capture system (18) will increase the competitiveness of CCPPs designed for CO2 capture and will allow earlier introduction of this kind of plants. The main objective of the present invention is to provide a method for the optimized operation of a CCPP with flue gas recirculation and CO2 capture system (18) as well as a plant designed to operate according to this method. To this end a combination of two parameters to optimize the overall plant efficiency is proposed. These are CO2 concentration in the flue gases, and the re- cooling temperature of the recirculated flue gases. Additionally it is found to be advantageous to control the flue gas flow, which is sent to the CO2 capture system (18). These parameters are given as functions over load to optimize the overall plant efficiency including the CO2 capture system (18). Besides the method a power plant designed to operate according to this method is subject of the present invention. Further, admixing of oxygen or oxygen enriched air to the gas turbine inlet gases (3) to enhance operatability is proposed.

摘要： A power plant (1) with a heat recovery steam generator HRSG (3), and a CO2 capture system (5) comprises a system for controlling the temperature of CO2 rich flue gases exhausted by the HRSG (3) and CO2 lean flue gases resulting from the CO2 capture system (5). The system comprises one single apparatus (4) for cooling the CO2 rich flue gases and a heat exchanger (6) to heat the CO2 lean flue gas, where the heat from the CO2 rich flue gas is used to heat the CO2 lean flue gas. The cooler (4) is configured to cool the flue gases from 70-140 °C down to a 10-50 °C, and the CO2 lean flue gas heater is configured to heat the flue gas from a temperature from 0-60 °C to 40-80 °C. The cooling of the flue gas enables CO2 capture at a temperature suitable for a given type of CO2 removal and the heating of the flue gas ensures buoyancy of the gas to be released through a stack (S). The system allows a full heat recovery and improves the overall performance of the power plant (1).

摘要： A combined cycle power plant comprises a system (9) for preheating inlet air to a gas turbine compressor and/or for fuel preheating (10a-b), where the fuel preheater comprises two or more stages. The preheaters are configured for the operation by means of heat from a CO2 capture system (21), from a CO2 cooling system (24, 24', 24"), from a heat consumer (12), from feedwater from a HRSG (5), from a heat exchange medium of a closed-circuit cooling system of the power plant, and/or from a flue gas cooler (20). The utilization of such heat in the preheater/s allows optimized thermal integration and increased overall power plant efficiency, in particular during part-load operation. A method of operating the power plant is proposed, where the gas turbine compressor inlet air is heated to a temperature above ambient in a range from 15 to 45°C.

摘要： The invention relates to a method for operation of a combined-cycle power plant (10) with cogeneration, in which method combustion air is inducted in at least one gas turbine (1 1 ), is compressed and is supplied to at least one combustion chamber (19) for combustion of a fuel, and the resultant exhaust gas is expanded in at least one turbine (20), producing work, and in which method the exhaust gas emerging from the at least one turbine (20) is passed through a heat recovery steam generator (13) in order to generate steam, which generator is part of a water-steam circuit (12) with at least one steam turbine (14), a condenser (32), a feedwater tank (28) and a feedwater pump (P2), wherein heat is provided by extracting steam from the at least one steam turbine (14). In a method such as this, the electricity production is decoupled from the steam production in that in order to restrict the electricity production while the heat provided by means of steam extraction remains at a constant level, a portion of the inducted combustion air is passed through the at least one turbine (20) to the heat recovery steam generator (13) without being involved in the combustion of the fuel in the gas turbine (1 1 ), and in that this portion of the combustion air is used to operate at least one supplementary firing (21, 23) in the heat recovery steam generator (13).

摘要： The invention relates to a method for operating a combined-cycle power plant (10) with cogeneration, in which method combustion air is inducted in at least one gas turbine (11), is compressed and is fed to at least one combustion chamber (19) for combustion of a fuel, and the resultant exhaust gas is expanded in at least one turbine (20) producing work, and in which method the exhaust gas which emerges from the at least one turbine (20) is fed through a heat recovery steam generator (13) in order to generate steam, which heat recovery steam generator (13) is part of a water-steam circuit (12) with at least one steam turbine (14), a condenser (32), a feedwater tank (28) and a feedwater pump (P2), wherein heat is produced by extraction of steam from the at least one steam turbine (14). In a method such as this, simple decoupling of heat and electricity production, which is advantageous for operation, is achieved in that the steam can be selectively extracted from the at least one steam turbine (14) as low-pressure steam or intermediate-pressure steam, and in that the steam extraction is switched from low-pressure steam to intermediate-pressure steam in order to restrict the electricity production.

The first steam drum is adapted to provide the flow of water and steam to a second steam drum. The second steam drum is in fluid communication with the first steam drum and receives the flow of water and steam from the first steam drum and separates steam from the flow of water and steam to form a separated steam. There is a steam flow outlet positioned in the second steam drum, the steam flow outlet adapted to release the separated steam from the second steam drum.
