阐述了光学波动法测量颗粒浓度的原理 ,并利用该方法在试验台上对管内煤粉浓度分布进行了测量研究 ,得出浓度分布规律。同时 ,分析了弯头对煤粉浓度测量的影响。研究结果对电站锅炉煤粉浓度测量具有指导意义
The principle of measuring the particle concentration by optical wave method is expounded. By using this method, the concentration distribution of pulverized coal in the tube is measured on the test bench, and the concentration distribution is obtained. At the same time, the influence of elbow on pulverized coal concentration measurement was analyzed. The result of the study is instructive for the measurement of pulverized coal concentration in power plant boilers
