摘要探讨了一种新型的300MW机组磨煤机制粉系统智能控制方法。

The paper reports the results of investigation for the operation condition of the ball-mill coal-pulverizing system of 100MW and larger power station. Based on the analysis of the ball-mill mechanism, the problem was found that the energy consumption on empty load of ball mill is more than 90% of the total energy consumption and the small iron balls that has lost mill ability and the iron component in the coal increased the mill s energy consumption. Thus automatic ball filter equipment was developed and in...

中文摘要：本文对我国100MW及以上火力发电厂磨煤机制粉系统现状进行总结、研究，指出存在的问题；分析了钢球磨煤机的工作机理，发现钢球磨煤机空载耗能约占90%以上，没有研磨效力的小钢球和煤炭中的铁件杂物加大了磨煤机耗能；研究开发了钢球磨煤机自动选球装置，并对50MW、100MW、200MW及300MW机组使用的钢球磨煤机进行改造，安装了该装置，通过改造前后的试验，证明该装置取得了明显的节能效果；在此基础上，对该装置提出了完善和改进措施。
