循環流動層における粉とガスの運動特性

抄録

In order to investigate the characteristic of the circulating fluidized bed reactor, a cold model experiment was made to evaluate the interaction force between gas and powders and a mathematical simulation model was developed to estimate the behaviors of powders and gas in the riser and the downcomer. As a result of these studies, it is predicted that the gas velocity must be set high at the riser to achieve a stable circulating flow of powders and to use raw material with larger distribution of particle size.
