Grades of Coal


Anthracite – this kind of coal has the greatest percentage of set carbon as well as a lower percentage of unpredictable material compared to all various other coals, making it more difficult to fire up. Nevertheless, when it is fired up, it burns relatively smokeless.The most popular anthracite mines in the United States are in western Pennsylvania.

Bituminous – Bituminous coal is one of the most abundant and most commonly utilized coals. This is the kind of coal found in the Appalachian area. It has a greater home heating possibility and also is used for making coke. It has a greater percent of fixed carbon, greater heat value as well as far better weathering attributes compared to lignite as well as sub-lignite coals.  Most of the non-metallurgical qualities of bituminous coal are burned in central heating boilers or heating systems to acquire thermal power for producing electrical energy. Since bituminous coal is softer than anthracite, it is usually referred to as soft coal. It does release smoke as it burns, unlike anthracite; however, there is an area in Southern West Virginia where the bituminous charcoal burns relatively smokeless. The Smokeless Coal Area of Southern West Virginia are one-of-a-kind on the planet.
