Abstract
A system for handling a bulk particulate material generally consisting of a vessel for holding a mass of such material; a first elongated tube formed of a gas permeable material, having an inlet communicating with such vessel; a second elongated tube formed of a gas impervious material encompassing the first tube and spaced therefrom about the periphery of the first tube; a plurality of transversely disposed, longitudinally spaced partitions disposed between said first and second tubes, forming a plurality of isolated chambers encompassing the first tube; each of such isolated chambers having means for selectively introducing a fluidizing gas therein independently of the other of such chambers, at variable volumes and pressures whereby the volume and pressure of fluidizing gas diffused through the first tube may be modulated along the length thereof; and means for injecting a flow inducing gas into the first tube.
