Abstract

The purpose of this paper is to show the potential for utilizing solar energy to dry fine coal waste so that this coal can be burned in industrial boilers. As much as ten percent of the raw coal processed in preparation plants ends up as fine coal particles mixed with water in disposal lakes called slurry ponds. Initial experimental tests on the solar dryer indicate that the drying of the coal by solar radiation occurs at a constant rate of about 7 to 12 percent per hour down to at least 5 percent moisture content during free convection drying conditions.
