Despite the body of work describing the performance of effervescent atomizers, its potential for use with coal water slurries (CWS) had not been evaluated prior to this study. This programs was therefore undertaken: to demonstrate that effervescent atomization can produce CWS sprays with mean drop sizes below 50 {mu}m; to determine a lower size limit for effervescent atomizer produced CWS sprays; to determine the mechanism(s) responsible for the formation of effervescent atomizer produced sprays. This report describes results of a mathematical analysis in order to better understand physical phenomena involved. 12 figs.
