摘　　要：提出一种基于Lambert-Beer定律,用激光作光源,经多光路在线监测烟气中烟尘(颗粒 物)浓度分布,统计浓度平均值求得烟尘排放量的方法.论证了该方法在理论上的正确性和在 实践上的可行性.可将该方法应用于一般情况下气固二相流有关参数的在线测量.Based on Lambert-Beer law and using laser as light source, in situ monitoring the concentration distribution of smoke (particulate) in fluegas through multi-light ways, and statistical average value of the concentration was conducted to develop a technique for measuring the output of the smoke. Its correctness in theory and feasibility in practice were proved. It can be also applied in general condition to in site measure the related parameters of two phase (gas-solid) flow.
