The combustion characteristics of coal slurry fuels in diesel engines: Detailed measurements and analysis

A program designed to address the atomization, ignition, and combustion problems associated with the use of slurry fuels in diesel engines is described. The program involves high-pressure injection rig and engine testing of three coal slurry fuels in Phase I, and modification of an existing analytical diesel engine heat release and pollutant formation model to include provision for coal slurry fuels in Phase II. The program approach and experimental facilities are discussed. The experimental testing portion of the program, which is currently in progress, is an extension of efforts conducted with three slurry fuels in a single-cylinder diesel research engine; the results of this previous program are described briefly.
