Emulsions of water and liquid fuels can burn better and cleaner than the fuels alone. This article rounds up that idea's full-scale applications to date, and reports on the widespread R&D still taking place. More information on emulsion fundamentals is needed. At least one major project has now been launched to fill the gap, a $120,000 National Science Foundation (NSF) research grant to Princeton University (Princeton, N.J.) scientists Irvin Glassman, Frederick L. Dryer and David W. Naegeli. One of the main aims is to characterize a "good" emulsion. Effects of particle size, water concentration, and total system pressure are just some of the unknowns. After two years or so on the fundamentals the team plans to focus on the diesel engine. At Adelphi University (Garden City, N.Y.), physics professor John Dooher plans to make photomicrographs of water/oil droplets actually shattering and to measure radiative heat transfer from the emulsion flame. Last summer, Dooher coordinated a session on emulsified fuels for a combustion workshop sponsored by the American Physical Soc., NSF, Federal Energy Administration and Electric Power Research Institute at the Princeton campus. About the only major effort to date in the U.S. has been a series of studies by Battelle Memorial Institute (Columbus, Ohio) during 1968-70, under contract to the National Air Pollution Control Administration (a predecessor of the Environmental Protection Agency). Battelle mainly looked into various techniques for preparing and characterizing emulsions of both No. 2 fuel oil with water and residual oil with water. Some limited combustion trials of the emulsions were also conducted.
