Abstract
125,689. Babcock & Wilcox, (Bell, J. E.). Feb. 28, 1918. Water-tube boilers; combined with industrial furnaces, kilns, and ovens; generating by indirect contact of heated gases.-In a water-tube boiler heated by the waste gases from an industrial furnace, kiln, or oven, the gases are drawn through the passes among the tubes by a fan so operating that, when the boiler is working at rated capacity, the weight of gas drawn per sq. ft. of average flow area is at least two thousand pounds per hour, and the desired draught is maintained at the outlet from the furnace &c. The Babcock-Wilcox boiler shown has additional rows of tubes and is fitted with vertical baffles 9 arranged so as to give three passes of equal sectional areas. The waste gases enter at the bottom 10 of the front pass and are drawn through the boiler by a fan 13. The inlet 10 may be connected to a by-pass flue leading from the stack of a regenerative open-hearth furnace, and the gases may be discharged through a branch flue 21 opening into the stack, dampers being provided to control the flow of gases into and from the boiler. In a Babcock-Wilcox boiler having 18 transverse rows of tubes and 10 vertical rows and fitted with vertical baffles giving four passes each of 12.2 sq. ft. area, the gases are drawn at a rate of 23,400 lb. per sq. ft. per hour, the draught produced by the fan being 3.1 inches, which, allowing a drop of say 1.32 inches in the boiler, gives a draught of about 1.5 inches at the furnace outlet.
