Filed: 1941-05-27
Abstract: 547,614. Pneumatic conveyers. HERBERT, Ltd., A., and JACKSON, R. May 27, 1941, No. 6768. [Class 78 (i)] In "ring" mains for supplying carburetted' air, e.g. air-borne pulverized coal, to furnaces &c. means is provided for ensuring uniform supply to the radial conduits. The type of main to which the invention is applied is that in which rotatably adjustable scoops 21 are located over the orifice of each conduit 13 to deflect part of the flow therethrough. A butterfly valve 16 controls the admission. The improvement consists in providing a baffle 26, having a converging top and sides, about each scoop 21, the inlet area of the baffle, at 32, being thus greater than the exit area, at 33. The baffle causes the 'eddy currents formed by the scoop 21 to die down before the flow reaches the next scoop. Two conduits 13 may be arranged side by side transversely of the main 11, and the baffle would then be a casting integral with the main 11, and have two upper and two lower ducts. The main section forms aT-piece with the conduit flange connection. Specification 547,615 is referred to.
