What are the elements and compounds of coal being mined

Anthracite burns the hottest among coal types roughly 900 degrees or higher and typically produces approximately 13,000 to 15,000 Btu per pound. Waste coal discarded during anthracite mining, called culm, contains approximately 2,500 to 5,000 Btu per pound.

Anthracite Coal Characteristics and Applications

Anthracite coal, mined from the planet39s oldest geological formations, has spent the longest time underground. The coal has been subjected to the most pressure and heat, making it the most compressed and hardest coal available. Hard coal contains greater potential to produce heat energy than softer, geologically 34newer34 coal.

Anthracite contains a high amount of fixed carbon80 to 95 percentand very low sulfur and nitrogenless than 1 percent each. Volatile matter is low at approximately 5 percent, with 10 to 20 percentashpossible. Moisture content is roughly 5 to 15 percent. The coal is slow-burning and difficult to ignite because of its high density, so few pulverized, coal-fired plants burn it.
