Abstract
PURPOSE: A coal slurry composition of low water content easily transportable and suitable as a fuel, which is prepd. by adding an unburned carbon particle formed by the combustion of a carbonaceous material to a slurry consisting of crushed coal and water.
CONSTITUTION: A fine unburned carbon particle formed by the combustion of a carbonaceous material is added to a slurry consisting of crushed coal and water. The fine particle used is carbonaceous and is not only effective for slurrying coal in high concn. but also harmless for the combustion of the slurry because it is combustible. The fine particle is, e.g., unburned carbon formed by the combustion of a hydrocarbon such as fuel oil, naphtha, diesel oil or gasoline. For example, an unburned carbon particle formed by the combustion of fuel oil has prticle size ≤ several μm and one formed from naphtha has particle size ≤ several μm, so that it is possible to use these in the state of a recovered material, without crushing, by mixing with the crushed coal.
