Effects of Particle Size Distribution and Packing Characteristics on the Preparation of Highly-Loaded Coal-Water Slurry

Patnaree Buranasrisak and Monpilai H. Narasingha

Abstract—The effects of particle size distribution and packing characteristics on the rheological behavior and solid loading of Coal-Water Slurry (CWS) have been examined in this study. The coal samples with six particle size ranges; i.e. < 38 μm, 38-63 μm, 63-75 μm, 75-90 μm, 90-180 μm and 180-250 μm, were used and three different packing characteristics were chosen for the experiments, i.e. monomodal, bimodal, and multimodal. The results showed that the coarse to fine ratio had an effect on the rheology of CWS. It is also found that, at the effective apparent viscosity, the bimodal packing characteristic with an optimum coarse to fine ratio can yield the highest in maximum coal loading for the prepared CWS with an accepting rheological behavior.
