The article present measuring techniques used in the analysis of phenomena that accompany the flows in circulating fluidized-bed conditions in a laboratory and an large scale. Most of consideration is given to noninvasive optical techniques, which arc possible to be used on pilot stands, as well as techniques used in the combustion chambers of large-power circulating boilers. The measuring capabilities of the techniques and examples of the obtained results are provided.
