Abstract
In a method for reducing wear on nozzles or other supply means when finely dividing a slurry consisting of a particulate absorbent suspended in water, in a reactor (5) for separating gaseous pollutants from flue gas containing fly ash, said flue gas with a substantial portion of its fly ash contents is introduced into the reactor to which the finely divided slurry is supplied and in which it is mixed with the flue gas. The water is evaporated and resulting reaction products as well as unreacted absorbent and fly ash are separated as a dry powder from the flue gas in the reactor (5) and/or in a subsequent filter (13), whereupon a portion of this separated material is classified so as to form a first fraction of fine particles and a second fraction of coarse particles, only the first fraction being recycled to the reactor to be used again. Before said portion of the separated material is classified, it is suspended in a liquid.
