Abstract (en)

In order to suppress the volatilization of phosphorus and improve melt treatment efficiency, a surface melting furnace 1 includes a furnace chamber 4, a treatment-target supply mechanism 8, and a edge portion of air-supply mechanism 20. The furnace chamber 4 includes auxiliary burners and air supply mechanisms 11 on the approximately center of its furnace ceiling 2, and has a slag port 3 a on its furnace bottom 3. The treatment-target supply mechanism 8 is configured to supply a treatment target to the furnace chamber 4 from a treatment-target container 7 disposed around the furnace chamber 4. The edge portion of air-supply mechanism 20 is configured to supply air toward the surface of the treatment target just having been put into the furnace chamber 4 by the treatment-target supply mechanism 8 to suppress reduction reactions of phosphorus oxides contained in combustible waste.
