WASTE INCINERATING METHOD IN FLUIDIZED BED INCINERATOR AND FLUIDIZED BED INCINERATOR

摘要

PROBLEM TO BE SOLVED: To satisfy the regulation value of dioxin by a method wherein the producing amount of dioxin in a furnace main body is reduced and a load for an exhaust gas treating device is reduced. ;SOLUTION: A screw conveyor 11 for supplying waste 7 from a waste hopper 8 into the upper part of a fluidized bed 2, formed in a furnace main body 1, is penetrated through the furnace main body 1 whereby the waste 7, passing through the inside of a casing 9, is pre-heated by heat generated by the combustion of the waste 7 in the furnace main body 1. Accordingly, the pyrolysis of the waste 7 is advanced in some degree at the time point when the waste 7 is supplied into the fluidized bed 2 whereby the waste 7 can be burnt completely in the upper part of the fluidized bed 2.;COPYRIGHT: (C)2000,JPO
