WASTE-INCINERATING METHOD IN FLUIDIZED BED INCINERATOR AND FLUIDIZED BED INCINERATOR

摘要

PROBLEM TO BE SOLVED: To satisfy the regulatory 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 9 for supplying waste 7 from a waste hopper 8 into a furnace main body 1 is opened in the lower layer part of a fluidized bed 2 in the furnace main body 1 to supply the waste 7 into the lower layer part of the fluidized bed 2, fluidizing the waste 7. The waste 7 is raised while being heated and passed forcibly through the inside of the fluidized bed 2. Accordingly, the staying period of time of the waste 7 in the furnace main body 1 at a high temperature place is increased whereby the waste 7 is burnt completely.;COPYRIGHT: (C)2000,JPO
