Feb 25, 2009 . Coals are raw materials for many chemical syntheses as well as cost-effective fuels for power plants due to their low cost; however, some coals such as lignite contain high amounts of moisture and/or ash. Coal currently fuels more than half of America's power plants. An estimated 45% of the world's coal.

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of.
This reduces the heating value of the coal as mined, which increases the transportation cost on a heating value basis and reduces the thermal efficiency of the steam boilers that use these coals. Most lignite mined in the United States is used in minemouth plants. Subbituminous coals, however, are generally transported.
