摘　　要：介绍了光脉动法的基本原理,及基于该原理开发的可用于直吹式和中间仓储式煤粉制粉系统的煤粉粒度和浓度实时在线监测系统。在某300MW电站锅炉1年多的长时间监测及在从300MW到600MW不同容量锅炉的制粉系统中的实验表明,该系统可以很好地监测煤粉的粒度和浓度。The principle of light fluctuation is presented, on which a novel system for on-line monitoring pulverized coal stream was developed by authors. This system can be used either in the direct firing pulverizing system or in the indirect firing pulverizing system. The results of over one year monitoring in a 300 MW utility boiler aad others show that the system can reliably measure the size distribution and concentration of pulverized coal.
