摘　　要：替代燃料与燃煤的C、H、O和水分、挥发分的含量差异导致其在水泥窑高温焚烧系统中的表现有明显差异,包括燃烧空气量、燃烧烟气量、有效热利用率等。在实际工业生产运行中,不能机械地将替代燃料的热量与煤粉热量进行等量核算。替代燃料的应用将导致系统风量及整体热耗的增加,会大幅度增加窑尾余热发电量。另外,替代燃料的品质关系到燃煤用量的降低幅度。The difference between the C、H、O and moisture volatile content of alternative fuel and coal combustion led to obvious differences in its performance in the high-temperature incmeration system of cement kiln,including combustion air volume,combustion flue gas volume,effective heat utilization rate,etc.In actual industrial production operations,the heat of alternative fuels cannot be mechanically accounted for in the same amount as the heat of pulverized coal.The application of alternative fuels will lead to an increase in the air volume and overall heat consumption of the system,which will greatly increase the power generation of waste heat at the end of the kiln.In addition,the quality of alternative fuels is related to the reduction in coal consumption.

关 键 词：替代燃料品质 热利用率 热耗 系统风量 余热发电
