    Is Your Coal Retaining Moisture Advancing Mining

    Mar 22 2016 The resultant coal is an extremely complex mostly organic generally well bedded sedimentary rock.. Because that coal originated in wetlands it can contain little or lots of moisture by the time it is mined. And the amount of moisture present in the coal dictates how the coal will be used. A USGS example explains that lignite is soft.

    Lignite contains 25–35 carbon and has the lowest energy content of all coal ranks. Lignite coal deposits tend to be relatively young and were not subjected to extreme heat or pressure. Lignite is crumbly and has high moisture content which contributes to its low heating value. Lignite accounted for 8 of total U.S. coal production in 2019.

    Environment Victoria Brown coal problem What is brown

    Victorian brown coal has a high moisture content containing more moisture than black coal – it can contain up to 70 percent water. This high moisture content makes long distance transportation uneconomic and so brown coal is not currently used for export markets. But that doesnt mean big polluting companies dont want to try.

    Drying coal is an endothermic process in which heat is absorbed and the temperature of the coal is lowered. The adsorption of moisture on a dry coal surface is an exothermic process with a heat producing reaction. If it is partially dried during its mining storage or processing coal has the potential to readsorb moisture thus producing heat.
