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