Abstract

A method for scrubbing flue gases of furnaces includes subjecting the flue gases with addition of activated carbon particles to wet scrubbing in a wet scrubbing device. Activated carbon particles are mixed with particles of at least one compound selected from slaked lime and limestone to produce a particle mixture that is introduced into the flue gases upstream of a flue gas heat exchanger that is positioned upstream of the wet scrubbing device.
