摘要

PROBLEM TO BE SOLVED: To provide a separator for incombustibles of a fluidized bed gasification furnace which separates incombustibles so as to increase the ratio of their effective utilization.;SOLUTION: This separator has a first classifying machine 11 for classifying the first incombustibles d1 discharged from the fluidized bed gasification furnace 51 for pyrolyzing and gasifying the wastes a to the second incombustibles d2 having a grain size below the first prescribed grain size and the third incombustibles d3 having the grain size greater than the first prescribed grain size, a first magnetic separator 14 for magnetically separating the second incombustibles to a first iron-component f and the fourth incombustibles d4 exclusive of the first iron-component, a second classifying machine 15 for classifying the fourth incombustibles to the fifth incombustibles d5 having the grain size below the second prescribed grain size and the sixth incombustibles d6 having the grain size greater than the second prescribed grain size, a third classifying machine 16 for classifying the fifth incombustibles to the seventh incombustibles d7 having the grain size below the third prescribed grain size and the eighth incombustibles d8 having the grain size greater than the third prescribed grain size and a flow passage for returning the seventh incombustibles to the fluidized bed gasification furnace 51.;COPYRIGHT: (C)2002,JPO
