Joint SNAME, IME And NYPE Meeting Discusses Use of Inexpensive Fuels A recent joint meeting of the New York Metropolitan Section of The Society of Naval Architects and Marine Engineers, the East- ern U.SA. Branch of the Institute of Marine Engineers, and The So- ciety of Marine Port Engineers New York heard a paper titled, "How To Utilize Inexpensive Fuel Efficiently in Modern Marine Die- sels." The authors were Ingmar Ahlqvist, technical section man- ager, and Rolf Vestergren, prod- uct manager, Wartsila Diesel, Fin- land. The paper and accompanying slides were presented by Mr. Ahlqvist to a large and obviously interested audience. The author began by stating that the only advantage of using the intermediate fuel oils, which are approximately 40 percent cheapter than marine diesel oil, is its lower price. In all other as- pects, he said, heavy fuel is disad- vantageous. He went on to discuss the properties of heavy fuel, in- cluding density and water content, viscosity, sulphur content, ash content, carbon residue, asphal- tenes, ignition quality, cracking catalysts, and compatibility. The author also evaluated the effects of each of these properties on the diesel engine and fuel handling system. "The ability to burn heavy fuel successfully lies in a purpose-de- signed diesel engine and fuel han- dling system. General considera- tions would include increased preheating of the engine before starting, including jacket water, lube oil, charge air, fuel system on both the high- and low-pressure side, and fuel nozzles; increased filter capacity of both fuel oil and lube oil; and higher temperature and improved insulation of the in- jection pump control system."
