摘　　要：在1 MW循环流化床试验台上,对垃圾衍生燃料(RDF)耦合燃煤进行了燃烧特性试验研究。结果表明:燃烧混合燃料1时SO2排放质量浓度为234.06 mg/m3,纯烧霍林河褐煤时SO2排放质量浓度为273.81 mg/m3,说明掺入RDF可以明显降低SO2的排放质量浓度;燃烧混合燃料时NOx排放质量浓度随着RDF掺烧质量分数的增加而升高,燃烧混合燃料3时NOx排放质量浓度达到350 mg/m3;燃烧混合燃料1时N2O排放质量浓度随燃烧温度的升高而降低;燃烧混合燃料1和混合燃料2时二噁英排放浓度均低于国家排放标准。Combustion characteristics of refuse derived fuel (RDF) coupled with coal were studied in a 1 MW circulating fluidized bed (CFB) test bench. Results show that, the SO2 emission of RDF-coal mixture 1 is 234.06 mg/m3, while that of Huolinhe lignite is 273.81 mg/m3, indicating that the addition of RDF helps to reduce the emssion of SO2. When RDF-coal mixtures are burned, the NOx emission increases with the rise of RDF blending ratio, and for mixture 3, the NOx emission reaches 350 mg/m3. The N2O emission of mixture 1 decreases with the rise of temperature. The dioxin emission of both mixture 1 and mixture 2 is lower than that specified in relevant national emission standards.
