Title:

COAL-WATER FUEL SLURRY AND MANUFACTURE

Document Type and Number:

Japanese Patent JPS58194989

Kind Code:

A

Abstract:

Coal-water fuel slurries having long-term storage stability and improved viscosities and comprising finely-divided coal having a particle size distribution which is 100% -50 mesh (-297 mu ) and at least 50% -200 mesh (-74 mu ) said coal being in an amount sufficient to provide a suitable coal concentration in the slurry so as to remain within efficient combustion size range, water, and minor amounts of alkali metal salts of organic dispersants to reduce the viscosity of the slurry and alkaline earth metal salts of organic dispersants to obtain a higher slurry yield point and provide a substantially stable static dispersion and a process for making such slurries.
