PCDDS PCDFS REDUCTION BY GOOD COMBUSTION TECHNOLOGY AND FABRIC FILTERWITH/WITHOUT ACTIVATED CARBON INJECTION/

In order to reduce polychlorinated dibenzo-p-dioxins (PCDDs) and polyc hlorinated dibenzofurans (PCDFs) in exhaust gases from MSW incineratio n plants, the treatment of the gases by using a fabric filter (FF) is available as one of the applicable methods. It has been reported that a FF removes not only particles and acid gases but heavy metals1). Our method using a FF enabled the efficient removal of PCDDs/PCDFs and me rcury in operating plants. In particular, the concentration of PCDDs/P CDFs was successfully reduced to 0.1 ng/m(3)N-TEQ.
