Abstract
The combustion and flue gas treatment system includes a furnace for combusting a fuel with an oxidizer generating a flue gas, ducting for the flue gas connected to a NOx removal unit and a SOx removal unit, and a recirculation line for recirculating a part of the flue gas back to the furnace. The SOx removal unit is located upstream of the NOx removal unit with reference to the flue gas flow. The recirculation line is connected to the ducting downstream the SOx removal unit.
