摘要： PROBLEM TO BE SOLVED: To achieve stable operation and decomposition of dioxin by raising the temperature of an exhaust gas.
SOLUTION: A plasma-type ash melting furnace is operated such that a plasma power is impressed on a carbon electrode 4 in an inert gas atmosphere which has been blown into a melting chamber 1a as a working gas to generate a plasma arc between a base metal 2 and the electrode, followed by heating and melting the ash fed onto the base metal 2, and that the resultant exhaust gas is discharged to a secondary combustion chamber for recombustion. At the time of operation, a predetermined amount of air for heating the exhaust gas is blown into the melting chamber 1a from an air nozzle 21 for heating the exhaust gas, so that the concentration ratio of oxygen to carbon monoxide of the exhaust gas at the exit of the melting chamber 1a does not exceed 0.30, thereby combusting a portion of the combustible matters in the exhaust gas in the furnace.

摘要： PROBLEM TO BE SOLVED: To provide a method which treats slag obtained by a high-temperature treatment of waste as it is raw to allow a molten lead salt to elute from the slag, and enables a decrease in lead content of the slag in an ash melting furnace. SOLUTION: In an exit of a melting cinder notch, the slag containing the molten lead salt is washed with an aqueous acid (pH2-5) to allow the molten lead salt to elute from the slag. The washing by the aqueous acid is preferably carried out for 40-60 minutes by stirring or flowage. As an acid, a hydrochloric acid, a sulfuric acid, a nitric acid, an acetic acid, a carbonic acid, an oxalic acid, a phosphoric acid, a formic acid, or the like is suitable.
