Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heating/melting processing apparatus having a structure wherein molten slag of a burned residue can be stably taken out, and a constituent member around an outlet can be prolonged in its life. SOLUTION: There are provided a cooling tube 6 for cooling a refractory member 3 around an outlet 9 through which molten slag 5 flows out, and a heater 7 for heating the molten slag 5 around the outlet 9. The heater 7 is graphite coated with SiC, a conductive MoSi2 composite sintered structure, a conductive ZrB2 composite sintered structure, or ones enclosed with a non- conductive refractory member, and is excellent in non-oxydation and slag resistant. The molten slag 5 is continuously stably taken out owing to heat of the heater 7 at the outlet 9. In contrast, a self-coating layer 10 is for med in which slag is solidified on an internal wall of the outlet 9, whereby the internal wall of the outlet 9 and the molten slag 5 are prevented from directly making contact with each other, and hence the refractory member 3 is prevented from being melted for its long time.
