Lignite - Wikipedia

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