ABSTRACT
Coal slurry fuels consist of finely ground coal dispersed into one or more liquids such as water, oil, or methanol. Slurry fuels have the advantages of being convenient to handle (similar to heavy fuel oil) as liquid fuel and processing high energy density, as illustrated in Table 4.1.1,2 Coal slurries have been investigated as potentially efficient replacement for oil in boilers and furnaces, fuel in internal combustion engines, and recently energy feedstock for cofiring of coal fines in utility boilers. Coal slurry is used around the world in countries such as the U.S., Russia, Japan, China, and Italy.
