Abstract

PURPOSE: To neutralize a slurry of coal and water at a pH of acidity and to prevent the corrosion of pipe line for transportation, by blending ashes obtained by burning an organic substance such as coal, etc. with water to give an alkali water, which is added to fine powder of coal to give a slurry.
CONSTITUTION: Ashes obtained by burning an organic substance such as coal, etc. are blended with water with stirring, and water which is made alkali by the ashes is separated from the ashes. The separated water is added to pulverized coal, which is slurried, and the slurry is adjusted to a pH in the range of neutrality by the alkali water.
