The rapidly moving steam,so to speak, carries the oil along on a flat jet like a spreadout fan and breaks upthe oil stream, separates it, and sprays itsparticles so that each one can be reachedby air and burned. The result is a power-ful flame reaching back a considerable dis-lance and with a slight upward curve dueto the- heat of cumbustion. As to the efficiency of oil as comparedwith coal, it is pretty well established thatthe British Thermal Units in petroleum willvary from 17,000 to 20,000, whereas goodbituminous coal has about from 13,000 to14,000 B. T. U. per pound. Mr. GeorgeK. Henderson in his book on Cost ofLocomotive Operation makes some inter-esting observations on the subject. Hesays: With a tractive effort of 20,000lbs. and a speed of 25 miles per hour, wewould burn 8,000 lbs. of coal and only 4,-000 lbs. of oil, or one-half as much. At15 miles per hour, however, and the force, we would use 3,000 lbs. of. DOING WELL, THANK YOU. coal and 2,400 lbs. of oil an hour, four-fifths as much due to the greater evapora-tive of coal at low rates of com-busion, Oil fuel is from 25 to 30 percent more efiicient than coal as a heat pro-ducer, weight for weight. The tender of that engine holds as wehave said gallons of fuel oil, and itcarries U. S. gallons of water. Itweighs when empty 66,000 lbs. The weightof th{- engine alone is 199,000 lbs.
