摘　　要：对YNLL水泥厂2500 t/d生产线进行热工标定并分析,系统烧成热耗为3889 k J/kg.cl,高于全国平均水平。高温风机拉风偏大,一级筒出口温度为370℃,偏高。篦式冷却机效果欠佳,AQC抽风量偏高,直接影响了熟料质量和余热发电量,热回收效率偏低。经过改进和优化,熟料产能提高为2600 t/d。该生产线系统还有比较大的潜力,熟料产量还有可能进一步提高,热耗及电耗均可能明显下降。Through analyzing the measured data of YNLL 2500 t/d cement production line, the heat consumption of sintering system is 3889 kJ/kg, el, which was higher than domestic level. High temperature fan has high air volume, the first stage outlet has got a slightly higher temperature at 370 ℃. The head kiln exhaust fan has high air volume and the poor cooling effect of grate cooler results in the low-quality clinker and low waste heat energy output and the heat recovery efficiency isn＇ t ideal. It is improvement and optimization the production line, the clinker output increased to 2600 t/d. The production potential is great. The clinker outputheat consumption and electricity consumption can be improved if production system is improved.
