The overall objective of this project is to perform experiments to understand the effect of coal beneficiation processes and high shear rheological properties on the atomization of coal-water slurries (CWS). In the atomization studies, the mean drop size of the CWS sprays will be determined at various air-to CWS. A correlation between the high shear rheological properties, particle size distributions and the atomization will be made in order to determine the influence of these parameters on the atomization of CWS. The viscoelastic behavior of several concentrations of the slurries under study: Heavy Cleaned, Flotation Cleaned and Uncleaned samples were measured. The results obtained will be correlated with the atomization data. The effect of the viscoelastic property on the atomization is being investigated further, and the results will be reported in the final report
