| Abstract: | At college of power engineering, USST, a technique based on analysis of fluctuating light transmission is being under study for real-time and on-line powder monitoring, which has been mainly applied to monitoring pulverized coal at power plants. This paper presents the fundamental of this technique and recent experiment results of powder fineness & concentration measurement by this technique performed with a simple setup. By analysis of these results, a simple new method is proposed for determination of particle size and concentration and its applicability has been discussed. |
