Abstract
The present invention relates to an apparatus and a method for melting incineration ash generated in an incinerator using a steam plasma torch which is capable of minimizing secondary pollutants and collecting calcium chloride from the melt. An exemplary embodiment of the present invention provides a method for treating incineration ash, including: generating a melt by melting the incineration ash comprising fly ash and bottom ash using a steam plasma torch; cooling the melt using water to dissolve molten salt included in the melt in the water and vitrify slag included in the melt; and collecting calcium chloride from the water in which the molten salt is dissolved.
