PURPOSE:To provide the titled fuel mixture which does not cause separation of coal and water during storage and is stable and excellent in combustion efficiency, by dispersing a carbonaceous solid fuel powder such as coal powder and a dilute aq. soln. of a water-soluble high-molecular compd. in heavy fuel oil. CONSTITUTION:Bituminous coal, coke, charcoal or activated carbon is pulverlized and screened to prepare a carbonaceous solid fuel powder. Separately, a water-soluble high-molecular compd. selected from among gelatin, methylcellulose, polacrylamide, starch, gum arabic and polyethylene glycol is dissolved in water to prepare a dilute aq. soln. of the water-soluble high-molecular compd. The carbonaceous solid fuel powder and the dilute aq. soln. of the water-soluble high-molecular compd. together with heavy fuel oil are introduced into an agitator to disperse them in the heavy fuel oil, thus obtaining the desired fuel mixture.
