摘　　要：在非均匀布风流化床中进行了半焦与垃圾衍生燃料(RDF)的混合燃烧实验,研究了不同半焦混烧率对烟气组分的影响以及二者混烧的可行性与经济性.实验结果表明,随着半焦混烧率的增加,H_2O(气态)、CO、HCl、NO及C_3H_6含量均呈下降趋势,而CO_2、SO_2含量则呈增加趋势.同时发现,在燃烧过程中增加Cl元素含量,可以促进NO的生成.The co-combustion experiments of semicokes with （RDF） refuse derived fuel were done in an internally circulating fluidized bed. The influence of different co-combustion rates of semicokes on the concentrations of gas constituents was studied. It is found that with the increase of the semicokes co-firing rates, the concentrations of H2O （g）, CO, HC1, NO and C3 H6 decrease, while the concentrations of CO2 and SO2 increase. Also it is found that the addition of the element C1 during the co-combustion can catalyze the formation of NO.
