Abstract: 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.

Abstract: 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).
