摘　　要：针对某公司4800t/d生产线预热器系统运行阻力大、C1出口粉尘浓度极高、分解炉系统CO高、系统运行不稳定等问题,进行预热器降阻、分解炉扩容、涡流室改造等系列改造,改造后,熟料日产量增加340 t/d,C1出口粉尘浓度(标况下)由120 g/m3下降至63.7 g/m^(3),C1出口负压降低至4 500 Pa左右,熟料标煤耗下降4.9 kg/t,熟料单位产品能耗指标达到能耗标杆水平,改造效果显著。In response to the high operating resistance of the preheater system,extremely high dust concentration at the C1 outlet,high CO content in the decomposition furnace system,and unstable system operation in a company′s 4800 t/d pro⁃duction line,a series of modifications were carried out,including preheater resistance reduction,decomposition furnace ex⁃pansion,and vortex chamber renovation.After the renovation,the daily output of clinker increased by 340 t/d,the dust con⁃centration at the C1 outlet(under standard conditions)decreased from 120 g/m^(3)to 63.7g/m^(3),the negative pressure at the C1 outlet decreased to around 4500 Pa,and the standard coal consumption of clinker decreased by 4.9kg/t.The energy con⁃sumption index of clinker per unit product reached the energy consumption benchmark level,and the renovation effect was significant.
