An experimental study was undertaken to investigate the rheological properties of coal-water slurries (CWS). Slurries were prepared from coal of different rank, different particle size distribution, additives and solid content. Viscosity at different shear rate were measured using a capillary viscometer specially constructed by the authors for this purpose. The stability of investigated CWS was performed too. The study has revealed a correlation between the rank of coal used for slurry preparation and its viscosity in all ranges of slurry concentration. The addition of some reagents causes a considerable decrease in the slurry viscosity. The stability of the slurry was improved too.
