In order to make good use of the effectiveness of a fluidized bed on thermal decomposition rate of solids, a basket elevator apparatus was manufactured for trial. A basket elevator is the improved apparatus of a fluidized packed (F. P. bed), having function of continuous operation. Dehydration experiments of natural gypsum were carried out in a F. P. bed and a basket elevator, and characteristics of each apparatus were examined. As a result, the style such as a F. P. bed or a basket elevator was confirmed to have practical application to industrial thermal decomposers of solids, having nearly same effectiveness as that for a single particle. Also, heat transfer coefficients (packed particle-fluidized bed), which is the most important parameter for such a contact style, were measured in a F. P. bed, and the conventional correlation was obtained.
