Coal Drying Methods 911 Metallurgist

In the past, it has more or less been a general rule that any time the total product is being washed, both mechanical and thermal drying was required. The reason for this was that a product moisture of 3 to 4% was required and thermal drying was and is the only practical method by which this can be accomplished. Some of the items which had to be considered in the economic study were the ...

Effect of Different Drying Methods on Coal Structure and

Effect of Different Drying Methods on Coal Structure and

May 21, 1996 Different methods of drying coal were investigated to determine if drying can be accomplished without altering the coal structure and reactivity toward liquefaction. Coal-drying methods included thermal and microwave drying at elevated temperatures and chemical drying at low temperature. Six coals from lignite to high volatile bituminous rank were studied. Laboratory-scale …

Thermal Coal Drying and Beneficiation Systems

Thermal Coal Drying and Beneficiation Systems

Convention flash dryers, with their high capacity and ability to handle very fine particles, are excellent for thermal drying of fine coals such as filter cakes or crushed coals (particularly those with high moisture contents and high evaporative loads). Moisture can typically be reduced to the inherent moisture level of the coal.

Coal Fines Drying. Created during the crushing and drying phases of coal mining, coal fines (particles smaller than 6mm) present disposal issues, as well as pose a health hazard to personnel and a contamination risk to the site. However, if processed correctly, coal fines can be converted into a fuel source, making them a valuable commodity. It is estimated that properly processed coal fines could satisfy more than 5% of the U.S. yearly demand for coal.
