PROBLEM TO BE SOLVED: To provide a method and an apparatus for removing chlorine from fly ashes to a chlorine concentration so low to be harmless in a cement firing chamber. SOLUTION: The method for removing chlorine from fly ashes involves eluting chlorine contained in fly ashes discharged out of a waste incinerator or melting furnace in water by crushing the fly ashes in water. The weight ratio (ash/water) of fly ashes and water is preferably 1/10 to 1/5. The fly ash treatment apparatus comprises wet-type fly ash crushing means for crushing fly ashes dispersed in water and eluting chlorine contained in fly ashes in water. COPYRIGHT: (C)2007,JPO&INPIT
