Effect of coal beneficiation process on rheology/atomization of coal water slurries. Quarterly progress report, January 1--March 31, 1993

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 paper discusses FTIR analysis, wet grinding, flotation cleaned coal, and heavy media cleaned coal
