Apparatus for melting waste

An apparatus for melting waste comprising a furnace body including a sideall made of anon-metallic material, an upper lid gastightly secured to an upper end of the sidewall, said upper lid having a waste supply inlet, a discharge outlet for exhaust gases and a bottom plate for closing a bottom portion of the furnace body;

• an induction heating coil provided at an outer peripheral portion of the sidewall;
• a waste melting vessel comprising a conductive ceramic material selected from the group consisting of C-SiC based ceramics and C-Al.sub.2 O.sub.3 based ceramics, said melting vessel being located on the bottom plate within said furnace body, whereby a current is induced in said waste melting vessel by said induction heating coil, such that said waste melting vessel generates heat to melt the waste, the waste melting vessel comprising a melt discharge pipe provided at a bottom portion thereof, the melt discharge pipe downwardly extending into the through hole in the bottom plate and further comprising a container which communicates with the discharge pipe for receiving the melt discharged from the waste melting vessel;
• and a shield which is suspended into the waste melting vessel to provide a predetermined space between a sidewall of the waste melting vessel and the shield.
