Lignite

Mar 05, 2002 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.get price

The most common classification is based on rank, referring to the degree of coalification that has occurred. The rank of a coal is determined primarily by the depth of burial and temperature to which the coal was subjected over time. With increasing temperature, peat is converted to lignite, a very soft, low-rank coal.get price

Coal

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.
