The invention relates to a method for removing SO2 from exhaust gas from sintering or pelletizing systems, wherein dry additive comprising one or more members of the group comprising adsorbent, recirculated material, and alkaline-earth-based reagent is added to an exhaust gas flow comprising the exhaust gas from a sintering or pelletizing system in an exhaust gas channel (1) in the entrained flow method, solids carried in the exhaust gas are subsequently separated from the exhaust gas by fabric filters (3) and are at least partially recirculated into the exhaust gas flow, and the exhaust gas is cooled and humidified in a controlled manner by introducing aqueous medium into the exhaust gas flow, wherein alkali-containing medium is added to the aqueous medium at intervals before the aqueous medium is introduced. The invention further relates to a device for performing the method.
