Abstract: 1,212,632. Degasification and distillation of water; direct-contact condensers. ALUMINUM CO. OF AMERICA. 19 March, 1969, No. 14540/69. Headings BIB and B1M. Water which contains non-condensible gas (e.g. absorbed air) is purified ;by feeding it into evaporator 26 (Fig. 4) which is maintained at sub-atmospheric pressure so that partial evaporation of the water and liberation of the gases take place; the vapour/gas mixture flows through passage 30 into the head 37 and chambers 38 where the gaseous mixture is formed into capsules each surrounded by distilled water, pumped into head 37 through pipe 44, and the capsules are forced down through chambers 38 and 54 wherei nthe water-vapour condenses, the gases being released from the liquid into the atmosphere when the capsules reach basin 39. Some of the distilled water is withdrawn from basin 39 through pipe 21, and the remainder is pumped back to head 37 via cooler 45. Heat may be added to the feed water in basin 24. Unevaporated water flows out of evaporator 26 through leg 28. Head 37 contains a perforated liquid-distributing plate, or packing. If mercury is used as encapsulating-liquid, the height of the apparatus can be reduced. In the apparatus shown in Fig. 10, the vapours from the evaporator (not shown) are first passed through condenser 31 in which a large proportion of the water-vapour is condensed, and the residual mixture of watervapour and gases flows into column 83 where it is formed into a foam with oil introduced through pipe 44. The foam is forced down the column and compressed by gravity, and the water-vapour condenses. When the mixture reaches basin 39, the gases are released and the condensate separates from the oil. Distilled water, to which a foam-promoting detergent has been added, may be used as condensing-medium in place of oil.

Title: Improvements in or relating to Furnaces Fed with Pulverulent Fuel.
IPC: F23C99/00
Filed: 1915-11-18
Abstract: 103,097. Porat, K. H. W. von, and Motala Verstads Nya Aktiebolag. Nov. 18, 1915. Pulverulent - fuel furnaces.-The fuel is introduced in one or more jets into a chamber wherein it is mixed with air and ignited by a fire or other device located at or near the rear end of the the chamber, the jet of fuel being deflected or reversed so as to pass along the vault forming the roof of the mixing chamber, and air being admitted at a point some distance from the point of admission of the fuel. With the arrangement shown in Fig. 1, the fuel jet from the nozzle 75 is deflected downwardly by the vault 74 towards the air inlet 79, and then divides, passing rearwardly and upwardly over the outlet from the igniting-fire grate 80, and so, crossing its former path, to the boiler tubes round the rear end of the vault 74, at the sides thereof, the middle portion of the vault being, if desired, continued backward as shown in dotted lines. Fig. 4 shows a modified arrangement in which the fuel jet is directed downwardly over the outlet from the igniting-fire towards the air inlet, the mixed stream of fuel and air being deflected rearwardly by the vault 74. In this case, there are two fuel jets side by side. Fig. 7 shows another modification in which the fuel pipes pass beneath the grate of the igniting-fire and deliver the fuel jets into diverging troughs 84. It is then mixed with air and deflected rearwardly by the vault 74. In all cases, there is a free space directly between the air inlet and the outlet from the mixing-chamber, and the air flowing in under the action of the chimney draught facilitates the movement of the fuel through the chamber. The space above the igniting-grate forms a separate chamber with a relatively narrow opening into the mixing-chamber. The air-admission openings may, as shown in Fig. 1, be formed between plates or the like arranged like a louvered window.
