The surface moisture of coal consists of the moisture absorbed in the pores and that adhered to the surface. The aim of this study has been to try to determine the individual effects of these two moisture components on the handling properties of a coal. The flowability of pulverized coal, at different levels of moisture content, has been measured using the widely accepted compression and shear method described by Jenike. The results showed that the moistures: total, absorbed, and adhered, had limited significance in the flowability of the coal samples. Instead, the conditioning history of the coal appeared to be the most important factor controlling the handling. 23 refs., 30 figs., 3 tabs.
