<p>The method involves allowing fumes (1) to be vacuum-cleaned, and denitrifying the fumes by mixing the fumes with a denitrification reagent such as urea (8). The fumes are mixed with denitrification catalysts (6, 7), and the fumes are introduced into a dust extractor (201). A fraction (5) of solids (3) is collected by the dust extractor. The denitrification reagent together with a flow of solids from a reactivation reactor (301) is recycled with fumes upstream of the dust extractor.</p> |
