Abstract
PURPOSE: To recover the coal particles from a coal-water slurry, with low power consumption, in high dehydration efficiency, effecting the recovery of a part of ash contained in the coal, by pelletizing the coal particles before recovery.
CONSTITUTION: (A) A coat-water slurry containing pref. 40W50% (dry base) of coal is mixed with (B) pref. 6W20wt%, based on the coal, of fuel oil and (C) pref. 0.01W5.0wt%, based on the coal, of a pelletizing agent. The mixture is adjusted to 6.5W10pH (or the pH of the slurry is adjusted beforehand), and stirred in a mixing vessel 1 to obtain pellets of a mixture of the coal particles and the fuel oil. The pellets are separated from water by the solid-liquid separator 7 to recover the coal particles from the slurry.
