Prediction of the Fountain Heights in Fine Particle Spouted Bed Systems

New empirical correlations are proposed to predict the fountain heights in spouted bed systems operating with fine particles. These correlations can be used for predicting the total spouted bed vessel height which is composed of the maximum spoutable bed height and the fountain height. It is important to be able to predict the total vessel height from the fluid and particle proporties and the spouted bed gemotery since further detailed information may not be available in the initial design stage. The fountain height correlations are developed for particles in the size range of 0.30 to 0.45 mm. The total vessel height is predicted by means of these equations and the maximum spoutable bed height correlations developed earlier.
