PROBLEM TO BE SOLVED: To provide a melting processing method and a melting processing furnace for waste in which upon directly melting waste the processing cost is reduced. SOLUTION: Air that is rich in air or oxygen from tuyeres 3, 4 at a single stage or a plurality of stages is blown into previously heat, dry, and thermally decompose waste, and thereafter alternating electric power is supplied to a heating coil 10 disposed on an outer periphery at a lower portion in the furnace, whereby a molded workpiece obtained by coating with ceramics graphite or cokes previously disposed at a lower portion in the furnace, or a molded workpiece obtained by blending carbon powder and ceramics, or a molded workpiece of electrically conductive ceramics is induction-heated to melt thermal decomposition residues in the waste. |
