摘要：The invention relates to a process for operating a glass-melting furnace, inparticular for the vitrification of waste materials polluting the environment, such asasbestos or asbestos-containing demolition material, sewage sludges, paint sludges,ashes, filter dusts and the like, a glass melt and, on top thereof, a mixed layer containingthe waste materials being present in the furnace during operation, the mixture being fedfrom the outside into the interior of the furnace, the required heat energy beinggenerated by heating devices in the glass-melting furnace, and the glass smelted fromthe waste materials and additives being discharged from the furnace through an outlet. Adisadvantage here is that large quantities of waste gas, which have to be purified, areformed and that the energy consumption is high. …To improve the process, it is proposedto produce a liquid scum layer of alkali metal salt or alkaline earth metal salt on thesurface of the glass melt and to maintain this in a layer thickness range corresponding tothe particular operating states of the furnace by discharge as required and/or to maintainthe mixed layer on the glass melt in a layer thickness range corresponding to theparticular operating states of the furnace by controlled introduction and distribution of
mixture in suitable compositions. …In this way, an improved heat transfer between themelt and mixture and extensive binding of waste gases into the scum and/or into themixture are achieved.
