Process for converting ash or combustion residues from radioactive or hazardous waste combustion equipment into glass-like leach-resistant products suitable for final storage

摘要

A process for melting ash and other ceramic materials having harmful constituents, such as, for example, radioactive or toxic materials as residues from an incineration plant having downstream waste gas purification, in which the heat energy contained in the flue gases downstream of the incineration plant itself is used directly for melting the ash or the incineration residues. In an apparatus for carrying out such a melting process, there is present in the flue gas line of an incineration plant, directly downstream of the latter, a melt pipe 8 taking up the residues 19, which pipe has the hot flue gases 4 flowing around it.
