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. … Lignite is the most harmful coal to human health.
Is brown coal better than black coal?
Brown coal (lignite) is classed as a low-rank coal because it has a high ash and moisture content, and less carbon, which means that it produces less energy when it is heated. … Black coals are ranked higher because they are harder, have more carbon, less ash and less moisture and thus a higher energy content.
