ABSTRACT:
A fuel slurry and engine systems for using the slurry are disclosed. The fuel slurry is a uniform mixture of water and 20 to 50 percent by weight of particulate coal of maximum size equal to 20 microns, the small size promoting complete combustion of the coal and minimizing engine wear due to particles of ash. Engine systems for utilizing the slurry of micronized coal and water are described, the preferred system including a slow-speed, two-stroke turbo-charged diesel engine. Preferred compositions of the fuel slurry are discussed and their behavior in engine systems is analyzed. Also disclosed are techniques for enhancing its ignition.
