The San Diego Section of The Society of Naval Architects and Marine Engineers opened its 1979-80 program year by holding its first meeting at the Naval Of- ficer's Club in San Diego, Calif. J. Thomas Schroppe, president of Foster Wheeler Boiler Corpora- tion, presented a timely paper titled "Alternative Fuels for Ma- rine Boilers." The marine boiler has been the workhorse of our merchant ma- rine for well over 50 years, but during the past 7-8 years, second thoughts have been given con- cerning this plant. This second look has been generated by oil crises of 1973 and the continual escalation of oil prices since that time. This paper offers coal as the alternate fuel, based on the abundance and the present eco- nomics. The paper focused on the pres- ent two options available to ship- owners for coal firing, which are the pulverized coal or stoker-fired systems. Coal burning methods, coal feed systems, air and gas systems and the environmental aspects, which are the major con- cern of both the shipowners and shipbuilders, were highlighted. The paper concluded with the op- erational and maneuvering condi- tions that can be expected with this fuel, and a brief on the fu- ture coal burning alternatives. The 50 members and guests in attendance concluded the meeting with a question and discussion period.
