摘要某5 000t/d水泥熟料生产线烧成系统原采用双系列五级预热器系统、三喷腾分解炉和带空气梁的第三代篦式冷却机。由于生产线运行时间较长，烧成系统存在预热器系统阻力偏高、C1出口温度偏高、窑头部分冷却风机用风不合理、出冷却机熟料温度偏高及热回收效率偏低等问题。结合对现场烧成系统的热工诊断结果，对运行过程中出现的问题进行了技术分析，制定了烧成系统优化方案，并从撒料装置调整、旋风筒扩容、分解炉扩容、更换高效节能风机、更换第四代带中置辊破篦式冷却机等方面开展了技术改造。技改实施后，系统能耗进一步降低，系统阻力减小，换热效率提升，达到了预期技改目标。

Abstract:

The pyro system of a 5 000t/d cement clinker production line originally used a dual series five stage preheater system, a three jet decomposition furnace, and a third-generation grate cooler with air beams. Due to the long running time of the production line, there are problems in the pyro system, such as high resistance of the preheater system, high outlet temperature of C1, unreasonable air usage of the cooler fans, high clinker temperature at the outlet of the cooler, and low heat recovery efficiency. Based on the on-site thermal diagnosis results of the pyro system, a technical analysis was conducted on the problems encountered during operation, and an optimization plan for the pyro system was developed. Technical transformation was carried out from the adjustment of the spreading device, expansion of the cyclones, expansion of the calciner, replacement of efficient and energy-saving fans, and replacement of the fourth generation grate cooler with middle roller crusher. After the implementation of the technical transformation, the system energy consumption was further reduced, the system resistance was reduced, and the heat exchange efficiency was improved, achieving the expected technical transformation goals.

Key words: pyro system spreading device heat exchange efficiency optimize technical transformation energy saving
