Anthracite Coal - High Carbon Content 22-28 Million Btu/ton | Hard, Compact, Low Moisture, High Heat Efficiency

Anthracite Coal

Anthracite is a hard, compact variety of mineral coal that has a high luster. It has the highest carbon count and is the best burning of all coals. Anthracite differs from bituminous coal in that it contains little or no bitumen, therefore it burns with an almost invisible flame. The purer specimens consist almost wholly of carbon.

It is hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter. The moisture content of fresh-mined anthracite generally is less than 15 percent. The heat content of anthracite ranges from 22 to 28 million Btu per short ton (26 to 33 MJ/kg) on a moist, mineral-matter-free basis. The heat content of anthracite coal consumed in the United States averages 25 million Btu/ton (29 MJ/kg), on the as-received basis (i.e., containing both inherent moisture and mineral matter).
