abstract: Coal-Water Slurry (CWS) is an attractive alternative fuel with lower cost and reliable in terms of transportation and handling. The efficiency of CWS gasification depends on the preparation of CWS to ensure the higher carbon contents and low viscosity which will enhance the heating rates along with the atomization of CWS. In this paper, the rheology of CWS was studied with coal loading 30 to 60 and the rheological behavior was discussed with the help of Power-law, Casson and Herschel Buckley models which shows that CWS exhibits pseudo-plastic (shear thinning) behavior. The CWS was prepared by using Poly-Vinyl Alcohol (PVA) and Triethanol Amine (TEA) as dispersants and Xanthan gum as a stabilizer. The experimental results showed that for a constant coal loading viscosity decreases as the shear rate increases and out of these rheological models, power-behlaw fits best on the experimental data with the highest R2 of 0.99. © 2019, Iranian Institute of Research and Development in Chemical Industries.
