CFBC and BFBC of lowrank coals ScienceDirect

Different from caking bituminous coals, lowrank coal particles maintain shape and size during ignition, devolatilization, and initial combustion, rather than coalescing into plastic blocks. Lowrank coals allow uniform release of volatiles over the outer surface and enhance its reactivity due to the high porosity.

What You Should Know About Metallurgical Coal

Caking refers to the coal's ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coal—generally classified as a metallurgical grade—is harder and blacker and contains more carbon and less moisture and ash than lowrank coals.

GE Technology for Dust Control in Coal Handling and Mining

Drying of LowRank Coal (LRC)—A Review of Recent Patents

2011103&ensp·&enspDespite being geographically dispersed, abundant, and accounting for almost half of the world's coal reserves, lowrank coals (LRCs) find limited use due to their high moisture content and high propensity for spontaneous combustion. Reducing the moisture content of lowrank coal

ASTM D388 19 Standard Classifiion of Coals by Rank

Note 1: Coals rich in inertinite or liptinite (exinite), or both, cannot be properly classified because, in those macerals, the properties that determine rank (calorific value, volatile matter, and agglomerating character) differ greatly from those of vitrinite in the same coal. Often such coals can be recognized by megascopic examination. In North America, these coals are mostly nonbanded

20181124&ensp·&enspThe world's total coal reserves are projected to last another 118 years*, but about half of these reserves consist of low rank coal (LRC). As increasing demand for high rank coal products places a burden on the available supply, utilization of LRC will become ever more important. Indonesia has vast reserves of coal, over 80% of which are LRC.
