Standard Test Method for Total Moisture in Coal

1.1 This test method covers the measurement of the total moisture in coal as it exists at the site, at the time, and under the conditions it is sampled. It is applicable to coals as mined, processed, shipped, or used in normal commercial pursuits. It is not applicable to coal-water slurries, sludges, or pulverized products under 0.5 mm-diameter sieve size.

The Moisture in the Coal is both these put together and is the “Total Moisture.” A coal sampled at the mines having a moisture of 20%, after storage for a few weeks, when entering the boiler can have moisture of only 8%. If the Coal sampled at the mines has an HHV of 18800 kJ/kg the same coal at the boiler will have a higher HHV.

Coal preparation plant Wikipedia

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

The Role of Coal Characteristics in Boiler Operation

Pulverizer capacity is particularly sensitive to coal moisture. An increase in coal surface moisture from 5% to 14% can reduce the output of the pulverizer to 74% of its original capacity. The Riley Stoker Corporation has found it desirable to use crusher dryers ahead of its ball tube mill pulverizers to overcome this problem.

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.
