Abstract: | An optical method for particle sizing in two-phase flow, the so-called light transmission fluctuation method, is presented in this paper. On the basis of this method, a novel optical instrument capable of in-line measurement of pneumatically conveyed particles is introduced. Quite a few medium-term tests validate the reliability and the applicability of this technique. Some measurement results are shown and discussed, concerning real-time in-line continuous monitoring of pulverized coal flow at coal-fired power plants and relevant laboratory experiments. |
