摘　　要：某水泥公司6 000t/d水泥熟料生产线存在电耗及标煤耗水平较高、分解炉炉容较小且利用率低、氨水使用量较大,冷却机热回收效率低等问题,各项运行指标均已接近设计水平。通过分解炉扩容、构建自脱硝系统、扩大各级旋风筒进口面积、更换新型撒料盒、将烟室升级为低阻低扬尘烟室、回转窑提速、采用步进式冷却机、更换大推力燃烧器等措施进行了节能降耗技术改造。改造后,熟料单位产品综合能耗降低4.9kgce/t.cl,每年可节约标煤1.2×10^(4)t,减少CO_(2)排放3×10^(4)t,节约氨水用量0.4×10^(4)t,实现了“能耗双控”下生产技术的全面升级。The 6000t/d cement clinker production line of a certain cement company has problems such as high electricity consumption and coal consumption,small capacity and low utilization rate of the calciner,high usage of ammonia water,and low heat recovery efficiency of the cooler.All operational indicators have approached the design level.Through the expansion of the calciner,construction of a self-denitrification system,expansion of the inlet area of each level of cyclone,replacement of a new type of spreading box,upgrading the inlet chamber to a low resistance and low dust inlet chamber,speeding up the rotary kiln,adopting the fourth generation cooler,and use high-thrust kiln burner,energy-saving and consumption reducing technological transformation has been carried out.After the technical transformation,the comprehensive energy consumption per unit product of clinker decreased by 4.9 kgce/t.cl,about 12000 tons of standard coal can be saved annually,30000 tons of carbon dioxide emissions can be reduced,and 4000 tons of ammonia water can be saved,achieving a comprehensive upgrade of production technology under the"energy consumption dual control".
