摘　　要：阐述了利用光学波动法测量颗粒浓度的原理,并在现场条件下,利用基于此原理的仪器对电站锅炉煤粉管道煤粉浓度分布作了测量研究,得出浓度分布规律,对电站锅炉煤粉管道浓度测量及分析电站锅炉稳燃、节能有指导意义。A novel basic method of processing the gas-solid two- phase flow is presented based on optics wave theory. The experiments are carried out to determine the pulverized coal concentration distributing of the gas-solid two-phase flow, exited from pulverized coal pipe of 660MW unit in power station. The results show that using this method to analysis steady combustion, make economical use of energy source and on-line measuring pulverized coal concentration is effective.
