华润贵港5000t/d燃无烟煤生产线预分解系统的设计与工程应用

Design and Application of the Precalcining System of 5000t/d Burning-anthracite Clinker Production Line of China Resources Cement(Guigang) Ltd.

分解炉是烧成系统的关键设备,尤其是对于燃无烟煤的分解炉,既要保证无烟煤粉在炉内的充分燃烧,又要利于系统的操作控制。基于分解炉煤粉燃烧机理,并通过分析影响炉内煤粉燃烧的各种因素及依据所用无烟煤的热失重分析结果,中材国际南京水泥设计研究院开发设计出了用于华润贵港5000t/d工程的喷旋管道式在线分解炉,并与高效、低阻、防堵的旋风预热系统组成了性能优异的预分解系统。从实际运行情况看,该预分解系统易于操作控制,且对物料适应性强、阻力损耗小。

Precalcinator is the key equipment in cement burning system, especially for the precalcinator burning anthracite, which not only have to guarantee completely burning of anthracite, but also have to benefit for the operation control of the system. Based on the coal burning mechanism in the precalcinator, by analysing all kinds of effect factors and according to the TGA result of the anthracite, Sinoma International NCDRI developed the on-line spout pipe caiciner for 5000t/d production line of China Resource Cement （Guigang） Ltd.. which composed an excellent-performance precalcining system combined with high-efficiency low-resistance and blockingproof cyclone preheater. According to the practice, the precalcining system is easy to operation and control and have the characteristics of high adaptability to raw materials and the low resistance wastage
