Processing Utilization Of Lignite Coal

Lignite an overview ScienceDirect Topics

Lignite, or brown coal, is the lowest-ranked coal, and is placed just above peat in terms of calorific value. It is not a feature of international seaborne coal trades, primarily due to its high water content (which can reach up to 60 per cent) and its lower Btu values (which average 4000–8300 Btu/lb compared with bituminous coals, which average 8500–14 000 Btu/lb).

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.
