A form of coal often referred to as â€œhard coal,â€ which is generally used in the production of steel, characterized by low volatile matter, low sulfur, low ash, low Hargrove index (indicating a hard coal) and high heating value. Sometimes blended with bituminous coal in sized coal cargoes to increase heating value. Heating value is often at or above 13,500 Btu/lb.
the highest rank coal. Very rare, found primarily in northeastern Pennsylvania. Known for its clean burning and smokeless characteristics. The demand for anthracite and the ability to transport it more efficiently by rail than by canal/barge was the chief reason the Philadelphia & Reading Railroad (predecessor of the Reading Co.) was chartered in 1833.
Anthracite (Greek Î‘Î½Î¸ÏÎ±ÎºÎ¯Ï„Î·Ï‚, literally "a form of coal", from Anthrax [Î†Î½Î¸ÏÎ±Î¾], coal) is a hard, compact variety of mineral coal that has a high luster. It has the highest carbon count and contains the fewest impurities of all coals, despite its lower calorific content.
