Abstract

Dispersion which comprises water, pulverized coal and additive and is stable in storage, can be pumped and can be burnt by conventional technique. The coal content of the dispersion ranges from 60 to 85% by weight and the dispersion contains at least one substance adsorbed to the surfaces of the coal particles, which provides repulsion between the coal particles by hydration forces.
