Abstract

This paper is based on the research of the coal water slurry rheological property and stability. The influence of the concentration, additives and temperature on the rheological properties of the slurry has also been studied. The apparent viscosity increases with increasing concentration of coal water slurry, and decreases with increasing temperature. An introduction of additives can greatly improve the rheological properties of coal water slurry. The stability of coal water slurry increases with the increase of concentration, and the stability decreases with the increase of temperature. A proper amount of additives can improve its stability.
