Coal Is Divided Into Four Classes Lignite Sub

Different Types of Coal
Bituminous Coal – This coal is dark and hard. This coal is formed when a sub bituminous coal undergoes a higher level of organic metamorphism. The carbon density of this coal is higher and accounts nearly 77 to 87 percent in a dry ash free basis; it is further divided into low volatile, high volatile and medium volatile types.

Coal Industry Archives
Coal is a burnable carbonaceous rock, classified as sedimentary. Coal is divided into four major types, based generally on the amount of transformation undergone from the earlier plant and peat stages, heating value and other characteristics: Lignite. A brownish-black coal with generally high moisture and ash content and the lowest carbon content.

Lignite
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat.It is considered the lowest rank of coal due to its relatively low heat content.It has a carbon content around 25 to 35 percent. It is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation.

KY Coal Facts
Coal Rank. Coal usually is divided into two main classes - anthracite (hard coal) and bituminous (soft coal). When anthracite was formed, it was squeezed under greater heat and pressure than was bituminous. As a result, anthracite contains the highest percentage of carbon and the lowest percentage of moisture.
