In order to elucidate the atomizing mechanism of Coal Water Mixture (CWM), several experiments on the atomization of CWM will be carried out with twin fluid atomizers. The effect of coal sizes on the formation of CWM spray droplets is investigated in detail. It is also found that large droplets of CWM spray consist of numerous fine coal particles and that large coal particles do not form "Nucli" of large spray droplets. From these experimental results, the breakup mechanism of CWM uneer high shear stress by gas-blasting at the exitport of the atomizer is proposed.
