METHOD FOR MELTING INCINERATION ASH

摘要

PROBLEM TO BE SOLVED: To inexpensively and assuredly prevent the production of sulfide from sulfur included in incineration ash when the incineration ash discharged from a waste incinerator is melted. SOLUTION: When the incineration ash is melted to reduce a capacity, converter slag generated in a steel making step is blended to melt the converter slag together with the incineration ash. At that time, the amount of the blended converter slag is preferably 100 to 150 kg per ton of produced molten slag. When the incineration ash to be melted is the incineration ash of source segregated combustible waste, its effect can be more exhibited.
