Abstract: 523,872. Pulverulent-fuel furnaces. BABCOCK & WILCOX, Ltd., and LULY, E. L. Jan. 17,1939, No. 1643. [Class 51 (i)] [Also in Group XIII] In a furnace for heating steam or other vapour by pulverulent fuel the primary air supplied to the burners is mixed with furnace gases having a temperature substantially lower than that of the furnace and in such proportion as not to extinguish the flame and further air is supplied to the furnace mixed with furnace gases having a temperature substantially less than that of the furnace and in proportion greater than that mixed with the primary air but insufficient to adversely affect efficient combustion of the fuel. The invention is described as applied to a plant comprising a steam generator furnace and a steam reheater furnace each fired with pulverized fuel the combustion products from which pass through a chamber containing an economizer and thence to an air heater the products of combustion from this chamber being returned to the reheater furnace mixed with air as stated above. Fig. 2 shows the reheater furnace provided with burners 53. Heated air from a conduit 65 passes through a pipe 68 under control of a damper 99 to a space 69 between inner and outer walls of the furnace and thence to the burners 53 for use as secondary air. Air also passes under control of dampers 67 through a conduit 66 to a conduit 73 and passes to the burners under control of dampers 74 and a further supply passes through a conduit 75 to the pulverizer 54 and thence to the burners with fuel for use as primary air. A fan 78 returns combustion products to mix with the air through a conduit 80 provided with a damper controlled branch 81 leading into the air conduit 66, a damper controlled branch 82 leading into conduits 86, 87 from which the gases are discharged under the control of valves through apertures 90, 91 in the inner wall of the furnace and apertures 93 leading into the space 69 surrounding the furnace and a branch 83 from which the gases are discharged through openings 96 and 97 into the passage leading to the superheater elements 56, 57 and into the'upper part of the furnace. The quantity of gases supplied by the fan is controlled by the gas temperature at the passage leading to the superheater as ascertained by a thermometer at 98. In a modification air and gases may pass from the space 69 through apertures in the inner wall arranged near the roof above the burners 53 instead of being led direct to the burners. The gases from the reheater furnace may be led to an open pass as described in Specification 523,871.

Filed: 1941-02-08
Abstract: 548,659. Vitamins. POTTS, H. E. (Distillation Products Inc.). Feb. 8, 1941, No. 1698. [Class 2 (iii)] In the extraction or purification of tocopherols from sludges or scums produced in the refining of animal or vegetable oils the tocopherol present is reduced from the quinone to the hydroquinone form prior to or during the extraction or purification. The reduction may be effected by catalytic hydrogenation or by chemical means such as a reducing metal, sodium and alcohol, sodium hydrosulphite and sodium phosphite. In the extraction or purification of tocopherols, the tocopherol is reduced to the hydroquinone form by chemical means. In examples (1) a scum condensed from the steam used to deodorize a vegetable oil such as hardened corn oil is heated with zinc dust and excess of caustic soda and the tocopherol is extracted from the solidified soap with a solvent such as ether or petroleum ether; to remove sterols the extract is evaporated and taken up with ethyl acetate which on cooling deposits the sterols; (2) a "hotwell sludge" from soy bean oil is heated with zinc, iron or aluminium dust and aqueous hydrochloric acid and tocopherol is distilled off under high vacuum ; (3) a crude high vacuum tocopherol distillate from an oil such as corn oil is dissolved in ethyl alcohol cooled to remove sterols, and treated with sodium amalgam in excess to saponify the fat ; the tocopherol is extracted from the soap by a solvent such as ether or petroleum ether. A mixture of reducing agents may be used such as stannous chloride and zinc dust. Specifications 452,442, 531,224 and 548,731 are referred to. Reference has been directed by the Comptroller to Specifications 546, 865 and 548,731.
