Abstract

981,179. Spray-producers. J. W. KECK. Oct. 30, 1961 [July 19, 1961], No. 38804/61. Heading B2F. [Also in Divisions F1, F2 and F4] The surface exposed to the hot combusition gases of direct-fired combustion devices are treated by injecting an aqueous slurry consisting, e.g., predominantly of water and magnesium oxide, against the surfaces (see Division F4) by a nozzle mounted on the combustion device. In the case of a steam boiler, soot blowers may be used which in addition to injecting pressurized cleaning fluid, such as air or steam, are then arranged to inject the treating slurry, the fluid being used at a lower pressure as a blowing medium for the slurry. A blower comprises a nozzle tube 36, Fig. 2, supported by a carriage 32 on an overhead rail 28 and movable from the retracted position shown by an air motor 34 which drives a gear 37 meshing with a rack 30 on the bottom of the rail. The rear end of the tube 36 carries a sleeve (not shown) provided with a driving sprocket whereby the tube is rotated as it is advanced into the boiler. The tube fits telescopically over a feed tube 39 to which the slurry is supplied via conduit 74. The pressurized fluid is supplied via valve 40 and the same or other pressurized fluid is passed also along an inner tube 54 and discharged into a seal formed by annular grooves which prevents leakage of the slurry between the tubes 36 and 39. The fluid and slurry are injected into the boiler through a pair of diametrically opposed nozzle holes 58. In operation, as the nozzle tube is moved forward, rods 62 on the carriage actuate cams to cause successive opening of valve 40 and a valve 78 in the slurry supply conduit. Thus the pressurized fluid is blown first through holes 58 and carries the slurry with it to be discharged into the boiler in the form of fine droplets. On the return movement of the nozzle tube, the slurry valve 78 is closed before the valve 40 so that the pressurized fluid has time to purge the tubes 36, 39 of any residual slurry. Holes 60 allow for drainage. In a modified construction, Figs. 5A and 5B (not shown), which obviates the need for the tube 54 and seal 52, the slurry is supplied to an inner discharge tube which opens into tube 36 and is swept forward by the pressurized fluid.
