华电大通双进双出钢球磨的自动调节

直吹式双进双出磨煤机系统在青海省内尚无投运经验,给调试和投运带来了一定的困难。在华电联合调试项目部多方人士的共同努力下,控制方案经过反复的修改,在调试过程中进一步完善和优化了磨煤机系统的各个环节的控制,终于使该系统得以成功投运。本文对直吹式双进双出钢球磨煤机工作原理、操作过程、运行特性进行了详细介绍,详细说明该类型磨煤机的启/停控制实现方法和本体保护,为此种类型的磨煤机操作和控制提供了一定的方法和经验。

Automatic Adjustment of Double Inlets and Outlets Ball Mill of Huadian Datong Thermal Power Plant

Because the double inlets and outlets ball mill system has not been put into operation in Qinghai province,thus the debugging and operation of system encounters some difficulties.Under the endeavor of Huadian associated project department,the system has been put into operation successfully,and each control part of the system has been perfected and optimized in debugging course.The paper makes a detailed introduction of working principle and operating character of direct-fired double inlets and outlets ball mill,and explains startup/stoppage control method and protection of the mill,and this provides a certain experience for control and operation of the same type mill.
