PURPOSE:To prepare a stable colloidal fuel in one step at low cost, by continuously pulverizing a carbide with a specific pulverizer and, at the same time, compounding the pulverized carbide with an oil and water. CONSTITUTION:An oil (e.g.: heavy oil A), water and an agent for dispersion and stabilization are homogenized in a mixing tank. The mixture is fed into a slurry tank. A carbide derived from a plant which has been pulverized into a powder of about 5 mesh or less is gradually added to the slurry tank. The slurry which has been homogenized in the slurry tank is fed into a first melt crusher in which the clearance of a mass colloider is set at 0.4-0.7mm and then fed into a finishing melt crusher in which the clearance of the mass colloider is set in the range of 0.01-0.03mm to obtain a colloidal fuel comprising particles of 30mu or less. It is preferred that the weight ratio of the carbide to oils be 35/65-49/51. A preferred amount of water is 10-20wt%. Further, it is preferred that the grinder provided in the crusher be made of a composite with a polymer.
