REFUSE EXHAUST GAS TREATING SYSTEM AND TREATING METHOD

摘要

A refuse exhaust gas treating system and treating method that are capable of reducing the amount of dioxin in exhaust gas without having to use drain water treating equipment. The refuse exhaust gas treating system is characterized by comprising a combustor for burning the incineration gas from incineration of refuse, a heat exchanger disposed downstream of the combustor to effect indirect heat exchange between the incineration gas and combustion gas flowing down from the combustor so as to cool the combustion gas, and a cooler disposed downstream of the heat exchanger to further cool the combustion gas that has passed through the heat exchanger.
