The salient technological properties of coal slurries are studied using fusel oil as the dispersion medium. The distinctive features of the rheological behavior and flow pattern of coal slurries as a function of the nature of coal are ascertained. It is shown that the effective viscosity of coal slurries decreases as the coal passes from the lignite to the anthracite stage. The calorific value and degree of combustion of coal slurries in fusel oil are higher than those of the original coal.
