METHOD AND APPARATUS FOR MELT TREATMENT OF BURNED ASH OF WASTE

PROBLEM TO BE SOLVED: To prevent uncombusted matters from incorporated into a slug in a melt treatment of a burned ash containing the uncombusted matter. SOLUTION: Air is fed from an air feeding pipe 8 to the inside of an incinerator body 2 of an induction heating device using a carbonaceous heating unit 4, thereby oxidizing and combusting uncombusted matters contained in a burned ash. Further, an exhaust gas treating device 21 is provided at the downstream side of a gas discharging port 7 so as to remove the uncombusted matters mixed into the exhaust gas. The exhaust gas treating device 21 consists of an induction heating device 20 using a nonconsumable metal heating unit 22. In this way, the uncombusted matters contained in the burned ash can be removed by combustion, thus suppressing the uncombusted matters from being taken in a liquid slug in the form of an unmelted state.
