The influence of material ratio and incineration temperature on the emission feature of main gaseous pollutants including CO、SO2、NO、HCl generated in the process of refuse derived fuel incineration was analyzed in order to effectively use refuse derived fuel prepared by the source-classified garbage. The results of Aspen Plus simulation and fluidized bed incineration experiment were compared. Results show that the CO mass concentration decreases and the NO mass concentration increases, but the SO2 mass concentration increases slowly with the plastic mass fraction increases in the RDF and levels off with the plastic mass fraction being 35%. The HCl mass concentration reaches the minimum with the plastic mass fraction being 10% and the minimum value is 260 mg/m3. The HCl mass concentration increases largely with the plastic mass fraction increasing from 35% to 45%, and the HCl mass concentration increases from 658 mg/m3 to 1021 mg/m3. With the incineration temperature going up, CO mass concentration decreases obviously. The CO emission mass concentration does not change when the temperature is 850 ℃. NO mass concentration increases largely and SO2 mass concentration increases slowly. The NO emission mass concentration does not change when the temperature is 850 ℃, and HCl mass concentration has an increasing trend.
