The present invention is provided with an exhaust gas reenactment loss for dioxins and deodorizing by small reproduce the exhaust gas generated when various waste incineration such relates to a waste incineration system with a exhaust gas reenactment disappeared, industrial waste, municipal waste, sludge It relates to a waste incineration systems. Waste incineration system with a exhaust gas reenactment dissipation according to the present invention, to dry the secondary combustion chamber and the secondary combustion of the waste to small reproduce the primary combustion chamber and a primary incinerated waste having an air supply and drying apparatus for, and a dust collecting device for collecting the exhaust the exhaust gas from the drying apparatus, according to a known consisting of a cooling device for cooling the dust collecting the exhaust gas, an exhaust for cattle reproduce an exhaust gas dust in the dust collecting device It characterized by the gas chamber reenactment installed in the hollow outer wall of the secondary combustion chamber. Thus, air as present and the waste incineration system with a exhaust gas reenactment dissipation according to the invention is that reducing the dust containing the generated during the incineration exhaust gas as well, and can eliminate the odor of the harmful odors such, dioxin reduction also the effect of preventing contamination, and the hollow wall of the secondary combustion chamber by using the exhaust gas without the need for a separate combustion chamber replay apparatus has the simple structure and the effect did less equipment cost. Waste incineration systems, exhaust, reproduce lost, hollow, exterior
