Proximate Analysis of Coal
The proximate analysis of a coal determines the moisture content, volatile matter (VM), ash and, by difference, the fixed carbon within the coal sample. It is the simplest and most common form of coal evaluation, and constitutes the basis of many coal purchasing and performance prediction indices used by utility operators.
