摘要： A fossil fuel fired power plant for the generation of electrical energy comprises a water steam cycle and a plant (10) for the capture of CO2 from exhaust gases emitted by the power plant and a steam jet ejector (24) configured and arranged to receive an input steam flow from a low- or intermediate pressure extraction point in the power plant and to increase its pressure. It is further arranged to receive motive steam (25) from a further extraction point in the power plant. A steam line (27, 22) directs the steam of increased pressure from the steam jet ejector (24) to the CO2 capture plant (10). The power plant according to this invention allows the use of low-pressure steam for the operation of the CO2 capture plant, where the extraction of such steam affects the overall efficiency of the power plant to a lesser degree than in power plant of the state of the art.

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 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： Since CO2 is identified as a main greenhouse gas, its capture and storage is essential to control global warming. Flexible operation of CCPPs (combined cycle power plants) with 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 increase the CCPP net power and improve the operating characteristics by taking advantage of the additional power and flexibility, which can be obtained with supplementary firing (10) in CCPPs with flue gas recirculation and CO2 capture systems (18). One particular aim is to minimize the impact of CO2 capture on the capacity of a power plant, i.e. to maximize the electric power the plant can deliver to the power grid. To this end an operating method, in which the power consumption of CO2 capture system is at least partly compensated by the operation of supplementary firing (10) in a HRSG (9) with low residual oxygen concentration in the flue gases (8), which is due to flue gas recirculation, is proposed. Further, additional ambient air and/or oxygen (11 ) injection into the supplementary firing (10) with corresponding operating methods are proposed. Besides the method a CCPP designed to operate according to this method is subject of the present invention.
