Abstract: A method for combustion of a fuel and treatment of the resulting flue gas includes: combusting a fuel to produce a hot flue gas stream containing at least carbon dioxide (CO2) and sulfur dioxide (SO2), bringing the flue gas stream into contact with solid calcium oxide (CaO) in a carbonation reactor operating at a temperature at which CO2 in the flue gas reacts with CaO to form solid calcium carbonate (CaCO3), heating CaCO3 in a calcination reactor operating at a temperature at which CaCO3 is converted to CaO and CO2, and recirculating CaO formed in the calcination reactor back to the carbonation reactor. Heating can be at least partially effected by indirect heat exchange with hot flue gas from the combustion. Flue gas used for the indirect heat exchange can be subsequently subjected to dry desulfurization before it is brought into contact with CaO in the carbonation reactor.
