2019/10/7Along with moisture and ash contents, the percentage of volatile matter in a coal sample is needed to calculate the fixed-carbon content of a coal. Many electric utilities prefer coals within a narrow range of volatile matter (25 to 35 percent) for optimal flame stability in the boiler (Thomas, 1992).
