摘　　要：介绍了LBTF 3200型篦冷机运行过程中存在的二次风温低、出篦冷机熟料温度高、热交换效率不理想等问题,分析了料层、冷却风机风压、风量对篦冷机性能的影响并提出了技术改造方案。技改后,二次风温平均提高40℃,三次风温平均提高68℃,窑头喂煤量平均减少0.5t/h,分解炉喂煤量平均减少0.2t/h,年节煤资金可达上百万元。This paper introduces the problems of low secondary air temperature,high clinker temperature and unsatisfactory heat exchange efficiency in the operation of LBTF 3200 grate cooler,analyzes the influence of material layer,air pressure of cooling fans and air volume on the performance of grate cooler,and puts forward the technical reform plan.After the technical reform,the secondary air temperature increases by 40℃on average,the third air temperature increases by 68℃on average,the coal feeding quantity of kiln head decreases by 0.5 t/h on average,the coal feeding quantity of decomposition furnace decreases by 0.2 t/h on average,and the annual coal saving fund can reach millions of yuan.
