Abstract
The combustion system includes a boiler and a flue gas treatment system downstream of the boiler. The flue gas treatment system includes a desulphurization unit, a carbonator and a calciner defining a carbonator/calciner loop. The flue gas from the desulphurization unit is fed into the carbonator. No air pre-heaters, for pre-heating combustion oxidizer to be supplied into the boiler using heat of flue gas, are provided at the boiler and between the boiler and the carbonator.
