Hydrodynamics of a Spouted Bed with an Impermeable Draft Tube for Binary Particle Systems
Nagashima H, Ishikura T, Ide M
A spouted bed with an impermeable draft tube was employed to obtain fundamental data of binary mixtures of glass beads for both the operating conditions and the design factors. These data were compared with those for the coarser particle system only. From this view point, minimum spouting velocity, pressure drop, holdup of solid particles within a draft tube, upward gas flow rate witnin the annulus and solids circulation rate were determined by changing the total gas flow rate and mass fraction of finer particles as operating parameters and by changing distance of entrainment zone and draft tube diameter as geometric parameters.
Keywords: Spouted Bed; Draft Tube; Binary Particle System; Minimum Spouting Velocity; Annulus Gas Flow Rate; Solids Circulation Rate
