310 heaters were placed at various points in the oil pipes to raise the oil to the proper temperature. A_ large heater was placed in the oil pipe suc- tion, another was placed in the dis- tributing pipe at the entrance to the shop, and two were placed in the attention to the regulation of the shop. This seemed sufficient, but dif- heaters. ficulties were immediately encount- Another serious fault with the or- ered.

Unless the following conditions are fulfilled, difficulties will be experienced in burning oil: -(1) The water must be effectively removed from the oil. (2) The oil must be uniformly heated, the temperature depending on the gravity of the oil. For oil of. 15 to 20 degrees gravity the tempera- ture should be from 115 to 120 de- grees Fahr. (3) There should be no long leads of dead pipes, allowing the oil to fall below the required temperature. The oil supply should form a circuit, so that surplus oil can be returned to the supply tank. (4) The oil in the supply pipes should be uniformly heated before the hour for beginning work in the shops. pa Ti V 7 BE} | = ak "3 rb--<-----<------<--}, < y QA [Js fa x ve i 3 H A ty 7 aut 1 { I! < = (8 a i a | | Ls | ; ot ne | | a Tong a 7 2B.

For the oil used, 15 to 20 gravity, a tem- perature of 120 degrees Fahr. should be maintained. In actual practice it was found that the temperature varied from 90 to 160 degrees. One fire was getting oil so cold that it could not be atomized, while at another fire the temperature was so high that carbon was deposited and the burner was clogged. Another difficulty experienced was due to cold oil in dead pipes. When the fires were started in the morning, cr if a forge not in use near the end cf a line was started, a satisfactory fire was not obtained until the cold ing water from the oil. It was at first considered that by settling the water in the main supply tanks and draining, no trouble would be ex- perienced. In practice it was found that frequently the fires were put out by water. I received but little aid from the shop in meeting these dif- ficulties. The foreman then employed had but little experience with oil, and he was no great advocate of its use, while the men openly opposed it. Un- der these conditions, as I was per- sonally responsible for the installa- tion, it was necessary for me to over- come the difficulties, and this was finally accomplished. (5) The oil pressure and the air pressure should be reasonably uni- form. (6) The burner used should be of a type that will not easily stop up, and should be easily regulated. Burn- ers suitable for the higher gravity oil used on the Atlantic coast are not suitable for California oil. General Arrangement of Oil and Air Apparatus.
