METHOD AND APPARATUS FOR RECOVERING WASTE HEAT OF REFUSE INCINERATOR

摘要

PROBLEM TO BE SOLVED: To solve the problem of high temperature corrosion due to adhesion of flyash to a boiler tube by enhancing the capturing efficiency of flyash significantly and to attain a high heat recovery efficiency. SOLUTION: Flyash in combustion exhaust gas is removed and hydrocarbon in combustion exhaust gas is decomposed thermally by passing high temperature combustion exhaust gas from an incinerator through a powdery filtering section 8. Heat is then exchanged between boiler water at a boiler section 7 and the combustion exhaust gas from which flyash and hydrocarbon are removed thus recovering heat of a refuse incinerator.
