Abstract
The invention relates to a method of treating power station residues in the form of bulk material, particularly the filter ash from power stations, by hydrating the lime content by adding moisture and by further wetting of the bulk material, with an opportunity for constantly feeding in material to be processed and discharging processed material, and also to an apparatus for carrying out the method. In order to provide a method and an apparatus by which large quantities of power stations residues (ash) can be quickly and safely treated at economic and comparatively low cost, it is according to the invention proposed that the bulk material supplied should pass through a succession of different spatially substantially separate treatment zones be moved mechanically at adjustable intensity throughout the entire process, be differently treated in each treatment zone, be caused to react and transported along a reaction line under control.
