4 Coal Mining and Processing Coal: Research and ...

Combined reserves of subbituminous coal and lignite (known as “brown coal” in the international coal trade) make up approximately one-half of the world coal reserves and about one-half of the coal resources of the United States. These coals are rarely processed before shipment or use. However, the oxygen and moisture contents of low-rank coals are greater than those of bituminous coals ...

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). The volume of the ...

Thermokinetics of Brown Coal during a Fluidized Drying Process

brown coal increases the e ciency of the system and reduces the production of carbon dioxide, greenhouse gases, and other gases harmful to humans [9,12]. The use of pre-drying of coal also brings measurable benefits associated with the reduction of the amount of coal burned, which will result in the possibility of extending the lifetime of coal deposits by up to several years [13]. The drying ...
