Coal utilization, Combustion of coal into useful solids, gaseous and liquid products. By far the most important use of coal is in combustion, mainly to provide heat to the boilers of electric power plants. Metallurgical coal is the major product of coal conversion. In addition techniques, for gasifying and liquifying coal into fuels or into feedstocks for the chemical industry are well developed, but their commercial viability depends on availability and price of the competing fossil fuels.
