Plawsky, Rensselaer Polytechnic Institute, Chemical Engineering, 110 Eighth St RI-122, Troy, NY 12180-3590 A new type of draft tube spout-fluid bed (DTSFB) is described in which the draft tube physically separates the particle feeder section from the particle separation section. This arrangement allows the fluid mass flowrate in the draft tube and the dynamic pressure drop across it to be independently specified. As a result, the solids mass flowrate can be varied by changing the solids fraction, the particle velocity or both. Equations are presented to show how this new DTSFB works and how the solids fraction and particle velocity in the draft tube are set and varied. The data of Grbavcic et al (Can. J. Chem. Eng. Vol. 71, pp. 895-905, 1992 are used to flesh out the design of a water driven bed. Extended Abstract Status: Not Uploaded | ||
