Lignite Wikipedia

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.
