To provide a waste melting furnace capable of melting waste by efficiently carrying out induction heating of a conductive substance in a hearth, and suppressing heating loss due to flowing of an eddy current in a furnace shell.
The waste melting furnace carries out induction heating by applying a high frequency current to the conductive substance filled in a furnace bottom by an induction heating coil 10 arranged in a furnace lower part. The furnace shell 15 is composed of a non-magnetic metal with low electric resistance, the induction heating coil 10 is installed in an outer side of the furnace shell 15, at least one portion in a circumferential direction of the furnace shell 15 is electrically isolated, vertical electric isolation of the furnace shell 15 from upper and lower metal furnace bodies is carried out by horizontally forming dividing parts 21 at positions in upper and lower end neighborhoods of the induction heating coil 10, and the dividing parts 21 are used as permeation paths of a magnetic flux into the furnace.
