The problem expounds in this study has heen discussed for a long time. This paper deals with the wear mechanism of the impact plate of fon shaped coal-mill φ 1070/291 produced by Wuhan factory 3551 and the problem to enhonce its wear resistance. The wear conditions at different spots of the impact plate are investigated by using a scanning electronic microscope. It is shown that the wear essence of the impact plate is that at the inlet and in the middle, impact wear predominates. It means that the running off metal at the impact plate surface is caused by the attack of coal grains, which results in impact hollows. Subsequently, the coal grains press the metal surface to form turn over cortices. As a result of repeated impact of a great number of coal grains, the turn over cortices form themselves into a numder of microrifts and at last, break away from the metal plate surface in the form of mill-chips. Yet at the outlet spot of the impact plate there is washout wear in addition to impact wear. At the some time wear experiment is also made for Almonite and some preliminary opinions are proposed.

提高风扇式磨煤机冲击板耐磨性是一个讨论已久的问题。本文对武汉3551厂的φ1070/291风扇磨冲击板磨损机理和提高耐磨性进行了研究,文中研究冲击板各部位磨损情况,通过扫描电镜对已磨损冲击板不同位置进行微观形貌观察得出,冲击板磨损实质是:在进口端和中间部位,是以撞击磨损为主。即冲击扳表而金属的流失是由煤粒撞击金属表面,形成撞击坑,并推挤金属形成翻皮,在大量煤粒多次撞击下翻皮形成许多微观裂纹,最后形成磨屑脱离金属板面。而在冲击板出口测,除撞击磨损外,还存在冲刷磨损。本文在分析磨损机理的基础上,还对阿尔玛铸铁进行了试验,并提出一些初步看法。

Based on a design and operation survey concerning drying agent constituents for fan mill pulverizing system of some domestic large capacity lignite-fired power plants, the author suggests that a mixture of hot air and high temperature gas should preferably used as drying agent for the direct-fired fan mill pulverizing system in Daqing Oil Field's House Power Plant.lt may also serve its purpose for other power plants.

本文是在总结了国内几座大容量褐煤电厂风扇磨制粉系统干燥剂组成配比的设计及运行实践的基础上,通过分析研究后提出大庆油田自备电厂风扇磨直吹式制粉系统的干燥剂,以采用热风、高温炉烟两介质组成为佳.可供电厂设计及运行参考.

For direct-fired-boilers with fan mill in thermal power plant, the automatic regulation of steam pressures remains long time a problem which has not been solved satisfactorily. But the solution of this problem is of great practical significance to the safe and economical operation of such boilers. This paper presents the investigation results of this problem, carried out in a power plant.

本文针对煤粉制备系统为风扇磨直吹制的锅炉主汽压调节对象的特点:惯性大、给煤机给煤量与控制电流呈非线性等因素,利用原有常规仪表构造降维观测器,提供超前反馈信号,提高了系统抗内扰能力,改善了调节品质。设计中使系统有较多的整定参数,以兼顾不同的性能指标。已在某电厂实际应用,并得到验证。
