Abstract
In a system for pneumatically conveying a bulk particulate material including a first conduit formed of a gas permeable material, a second conduit formed of an impermeable material encompassing and spaced from the first conduit, a plurality of partition walls disposed between said conduits and spaced along the lengths thereof providing a plurality of plenums, means connectable to a first source of gas under pressure for injecting a gas under pressure into said first conduit to impel material deposited therein and second means connectable to a second source of gas under pressure for supplying gas under pressure into said plenums to fluidize material flowing through the first conduit, a system for declogging the second conduit consisting of means connected to a source of gas under pressure operable for selectively supplying the plenums with bursts of gas under pressure for dislodging material deposited in said apertures of the first conduit.
