Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
124 words
In combination with a system for conveying gas entrained particles, the system including a disperser comprising tubular-walled inlet and outlet members, the inlet and outlet members having at least portions thereof concentrically disposed and spaced from one another to form an annular channel therebetween, plate means closing the bottom of the annular channel, the inlet member defining a central channel for admitting gas entrained particles to the disperser, the outlet member having at least one wall opening, and the inlet member having a plurality of wall openings located above the wall opening of the outlet member, and means communicating with the outlet member wall opening for supplying a pressurized gas to the annular channel to disperse the gas entrained particles exiting from said channel.
