Abstract: 723,849. Washing gases. CAPUANO, S. D., and PONDAL, A. G. Dec. 2, 1952, No. 30593/52. Class 55 (2). An apparatus for removing soot from combustion gases consists in one form of a rectangular chamber 3 in the top portion of which is positioned a sprinkler pipe 5, the chamber having a lateral gas inlet 2 and a bottom outlet duct 4, the latter extending vertically to a separating chamber 7 which is partly filled with water and terminating a short distance above the water level. The chamber 7 has a gas outlet 9 in which may be mounted an induced draught fan 16. In operation, water is supplied to sprinkler 5 from a storage tank 6 and forms a curtain through which the soot-laden gas entering chamber 3 must pass to reach duct 4. The gas and water flow down the duct 4, the gas impinging on the surface of the water in chamber 7 so that the soot is retained thereon. The clean gas is withdrawn through outlet 9 by fan 16, first passing through an additional spray from a pipe 13. Water overflows from the chamber 7 at 14 and is recirculated to tank 6 by a pump 11. In a modification, Fig. 4, the chamber 3 is cylindrical and contains a conical baffle plate 17 beneath which sprinkler pipes 5a and 5b are positioned. Water from the sprinklers collects around the top 19 of duct 4 which extends upwardly into the chamber and passes through openings 18 into the duct, flowing downwardly into a second sprinkler chamber 21 and thence into the chamber 7. The gas passes through both sprinkler chambers to chamber 7 wherein it is constrained to pass across the surface of the water by a collar 25 provided at the bottom of duct 4.

Title: Improvements in or relating to tubulous vapour generating and vapour heating units
IPC: F22G5/06
Filed: 1956-10-11
Abstract: 803,903. Regulating steam temperature in boilers, BABCOCK & WILCOX. Ltd. Oct. 11. 1956 [Oct. 26, 1955(3)] No. 30970/56. Class 123(3) In a water-tube boiler comprising a gas recirculating system for effecting regulation of steam temperature, reverse flow of hot furnace through the recirculating fan is prevented without increasing the size of the fan or its power requirements by providing for an auxiliary flow of gas or air through the fan at times when the danger of reverse flow exists. The recirculated gas system is shown applied to a boiler of the form described in Specification 726,244. It comprises a recirculating fan 26 which withdraws cooled flue gas from the bottom of a downpass through a duct 28 and delivers it to the secondary furnace 22 of the boiler through ducts 30, 32, and an opening 34 at a rate controlled by dampers 36, the setting of the latter being automatically adjusted in response to changes in superheated steam temperature and boiler load by a control system such as that described in Specifications 729,437, 738,021 or 758,374. In general, the flow of recirculated gas is increased as the boiler load dcreases, with a minimum flow at high loads. With a sudden increase in load or with abnormal slagging of the boiler tubes, the pressure differential between the recirculated gas opening 34, position H, and the outlet from the fan 26, position I, may decrease to a value, about 1¢ inches W.G., at and below which there is apt to be a reverse flow of hot gas into the fan. Under these conditions a controller 54 connected between points H and I actuates a relay J which causes an alarm M to sound and dampers A and D to open sufficiently to permit such flow of cold air from the boiler forced draught fan 50 through ducts 102, 67 to the inlet of the fan 26 that it can exert an increased forward pressure and thereby restore the pressure differential bteween H and I to a value well above 1¢ inches W.G. If, with the dampers A, D wide open, the pressure differential continues to fall, a pressure switch K is actuated by the relay J to stop the fan 26, to close dampers E, C. thereby isolating the fan and to open a damper B to permit a direct flow of cold air into the furnace 22 through ducts 100 102, 32. In the event of failure of the other controls, the dampers C, E are closed and the damper B opened when a dangerous rise of temperature within the opening 34 occurs as sensed by an element 110. In a modification, Fig. 2, not shown, a damper-controlled by-pass is provided between the outlet and inlet of the fan 26 to augment the flow of cold air to the fan inlet by a recycled gas flow.
