method for the treatment of residues of a waste incinerator, and waste incinerator for carrying out the method

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. IMAGE
