Abstract

The present invention relates to a process for treating lime sludge formed within the causticizing plant in a pulp factory, which lime sludge is concentrated in a lime sludge filter and burnt in a lime kiln. A part of the concentrated lime sludge is dried and preheated by means of the flue gases of the lime kiln, is separated out from the flue gases and is fed into the feed-in end of the lime kiln. In order to cool the constructions at the feed- in end of the kiln, a part of the lime sludge is fed past the flue gas treatment direct to the feed-in end of the lime kiln. <IMAGE>
