Abstract

The trajectories of the particles in conical spouted beds are determined from the vertical component of velocity measured by means of an optical fibre probe and from the horizontal component of velocity calculated by solving the mass conservation equations for the solid in differential volume elements in spout and annular zones. From the experimental measurement of solid flow rate along the spout, the solid cross-flow rate from the annulus into the spout is determined. In this paper the effect of the solid density and solid shape on the solid circulation rate along the spout and on the solid cross-flow into the spout zone has been analysed by carrying out the operation with solids of different density and shape.
