Abstract
Process for combustion and vitrification of waste in which at least one oxygen plasma jet is associated with a continuous melting device by high frequency direct induction. The crucible is composed of a continuous external shell and a sole plate, both cooled by a liquid circulating in internal channels. The inductor is placed below the sole plate. There is a gravity drain valve at the bottom or on the side.
Claims5
A vitrification process using a furnace comprising a crucible and heating means comprising at least one plasma torch on an upper part of the crucible and at least one inductor winding under the crucible;
- wherein the plasma is an oxygen plasma, which creates an oxidizing atmosphere in the furnace.
