VERFAHREN ZUM BEHANDELN VON RUECKSTAENDEN EINER ABFALLVERBRENNUNGSANLAGE UND ABFALLVERBRENNUNGSANLAGE ZUR DURCHFUEHRUNG DES VERFAHRENS

摘要

The invention relates to the treatment of residues, such as grate ash, boiler ash and flydust from a waste incineration plant. It is known to collect the residues and to melt them in a melting furnace. In this case, however, metals and metal compounds remain in the slag produced, so that the re-utilisability of the latter is restricted. The invention is intended to improve the re-utilisability of the slag. A melt enriched in metals is additionally tapped from the melting furnace. A completely glassy slag which can be used, for example, in road construction is thus formed from the remainder of the melt.
