FLUIDIZED BED TYPE GASIFICATION MELTING FURNACE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a gasification melting furnace device for individually optimally holding the temperature of a gasification furnace and a melting furnace to a change in garbage quality. SOLUTION: This fluidized bed type gasification melting furnace device has a fluidized bed type gasification furnace 5 for pyrolyzing and gasifying garbage, and the melting furnace 13 for burning combustible gas and combustible particulates generated by pyrolysis of the garbage at the high temperature; and variably adjusts the supply ratio of auxiliary fuel quantity and auxiliary air quantity by supplying auxiliary fuel 9 and auxiliary air 11 to the gasification furnace 5. An auxiliary fuel input port for supplying the auxiliary fuel to the gasification furnace is arranged in a space part of a fluidized bed upper part or a fluidized bed; and supplies the auxiliary air supplied to the gasification furnace in the fluidized bed by adding to fluidizing air to the space part or a diffuser pipe of the fluidized bed upper part. An auxiliary fuel flow rate to the gasification furnace is adjusted on the basis of the melting furnace temperature by detecting the temperature 14 of the melting furnace. The auxiliary air quantity is adjusted on the basis of the fluidized bed temperature by detecting the fluidized bed temperature 8 of the gasification furnace. COPYRIGHT: (C)2005,JPO&NCIPI
