MELTING TREATMENT METHOD OF REFUSE INCINERATION ASH AND MELTING TREATMENT INSTALLATION

摘要

PROBLEM TO BE SOLVED: To provide an installation which is high in thermal efficiency, small in power consumption, simple in structure and seldom to cause breakdown, and to make the best use of high carolific value waste matter, and generate molten slag having stabilized properties. ;SOLUTION: An ordinary refuse incinerator 1 which specifically burns ordinal refuse from which high temperature carolific value waste matter is separately removed is combined with a high temperature incinerator 4 which exclusively burns high carolific value waste. A high temperature furnace exhaust gas 62 in an imperfect combustion state discharged from the high temperature incinerator 4 is secondarily burnt in a secondary combustion chamber 46 located above a melting device 3 to produce a melting device gas 63. By using the radiation heat of this melting device gas 63, incinerated ashes 81 discharged from the ordinal refuse incinerator 1 and the high temperature incinerator 4 are processed by melting.;COPYRIGHT: (C)1997,JPO
