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 ...

dry cleaning process, these emissions are generated when the coal is stratified by pulses of air. Potential emissions from wet cleaning processes are very low. The major source of emissions from the final preparation phase is the thermal dryer exhaust.

review of coal lignite dry cleaning process

Three product streams, i.e., clean (deshaled) product, middlings and tailing streams are generated during the separation process. An air collection system is employed to clean the recycled air and to remove the dust from air being emitted into the atmosphere. This makes FGX separators cleaner than other coal processing methods.
