What is the most abundant type of coal in the US?
Bituminous is the most abundant rank of coal found in the United States. Bituminous coal accounted for about 44% of U.S. coal production in 2020. Anthracite contains 86%鈥?7% carbon and has a heating value that is slightly higher on average than bituminous coal.
What is the best type of coal to use?
The coal with the highest carbon content is the best and cleanest type of coal to use. As you move down the coal rank the heat given out decreases and the dirtiness of the fuel and moisture content increases. Used almost exclusively for electric power generation lignite is a young type of coal.
What is the rank of a coal?
The rank of coal is based on the degree to which the original plant material has been transformed into carbon and can be seen as a rough indication of how old the coal is: the older the coal the higher the carbon content (generally).
Which type of coal has the lowest energy content?
Lignite is the lowest rank of coal and has the lowest energy content. Lignite is crumbly and has high moisture content. Lignite accounted for about 9% of U.S. coal production in 2020.
