Refined coal Wikipedia

Refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned.

Evaporative Drying of Low-Rank Coal IntechOpen

Low-rank coals including the brown and the subbituminous coals are commonly known to contain high moisture content (up to 65%, wet basis), which limits their utilization around the world in spite of their low cost. Today, the most of the drying technologies are based on the evaporation of the water from the moist product. In this chapter, the most effective parameters on the evaporative coal

Coldry Overview ECT

Based on research initially conducted by CRA and the University of Melbourne in the early 1980s, the technology Coldry is a patented process that changes the naturally porous form of brown coal to produce a dry, dense pellet, via a process called ‘brown coal densification’. The Coldry process offers benefits, including:
