Abstract
Plasma Melting Technology enables effective melting of PCB-contaminated wastes together with their container drums at one time, by using plasma arc and molten slag bath in the plasma melting furnace with plasma heat source. A series of verification tests to treat PCB-contaminated wastes are carried out in the test facility. These results offered a stable operation and discharge of homogeneous slag to be recyclable. And furthermore, the concentrations of PCBs and Dioxins in the slag, fly ash and flue gas from plasma melting furnace were substantially less than the Japanese regulations. It is proved that the Plasma Melting Technology could not only treat various PCB-contaminated wastes but also minimize the PCB contamination on environment and field workers.
