ASH MELTING FURNACE ARRANGEMENT AND METHOD FOR SUPPLYING ASH TO ASH MELTING FURNACE

摘要

A dry sorting (12) machine having a separating function for removing solids of more than apredetermined size from ash and a drying function for drying the ash, and a magnetic sortingmachine (14) for removing metals from the dried ash are arranged in a pretreatment route forthe ash to be supplied to the furnace (2). Further, there is provided a drying air pipe (50) forintroducing the high-temperature air heat-recovered from exhaust gases discharged from theash melting furnace into the dry sorting machine. Thus, by the dry sorting machine having theseparating and drying functions, simplification of the ash pretreatment process and reductionof the installation space can be achieved.Fig. 1
