The inside of the tank proper 3 is divided by a partition 7 into a thermal decomposition chamber at its front and a melting chamber at its rear, with a communicating space to connect the thermal decomposition and melting chambers and provided below the partition. Heating pipes are disposed in the tank proper so that hot air travels from the thermal decomposition chamber through the communicating spaces to the melting chamber. This arrangement permits keeping the thermal decomposition chamber, communicating spaces and melting chamber at temperatures suited for thermal decomposition and melting, thereby realizing design simplification and size reduction, permitting substantial cost savings and ease of maintenance, and increasing productivity and economy.
