Vitrification furnace and method with dual heating means

摘要

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 ( 4 ). The crucible is composed of a continuous external shell ( 1 ) and a sole plate ( 2 ), 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.
