煤粉管道及制粉系统的运行状况对锅炉燃烧及安全运行有很大影响 ,但一直缺少有效的检测诊断。基于静电原理的在线检测是一种新型的煤粉细度测量技术 ,通过测量管道中煤粉空气两相流动时产生的静电电荷 ,经过有效的信号处理 ,提取管道中煤粉粒度信息 ,系统在标定后可实现煤粉细度的在线测量 ,进而监测和指导磨煤机运行
The operation of pulverized coal pipelines and pulverizing systems has a great impact on the combustion and safe operation of boilers, but there has been a lack of effective detection and diagnosis. Based on the electrostatic principle of on-line detection is a new type of coal fineness measurement technology, by measuring the two-phase flow of pulverized coal in the pipeline when the electrostatic charge generated, through effective signal processing, extraction of coal particle size information in the pipeline, the system in After calibration, the fineness of coal can be measured online, and then monitor and guide the coal mill operation
