It is brownish-black and has a high inherent moisture content, sometimes as high as 66 percent, and very high ash content compared to Bituminous Coal . The heat content of lignite ranges from 9 to 17 million Btu per Short Ton (10 to 20 MJ/kg) on a moist, mineral-matter-free basis. The heat content of lignite consumed in the United States averages 13 million Btu/ton (15 MJ/kg), on the as-received basis (i.e., containing both inherent moisture and mineral matter).
