Fine Coal Moisture: not familiar with this term. I assume it is the Total Moisture in the fine fraction of coal. Fine fraction or "fines" is sometimes defined as the .5 mm f … raction. "Inherent Moisture" is a non-preferred term according to Australian Standard 1995: Coal & Coke - Glossary of Terms.

Moisture of incoming coal ranged in the 4% to 7.5% range, with 6% moisture the desired level. Coal is transported on a inch belt at about 275 tons/hour into a coal silo, prior to entering a hammermill, sized under two inches and at about a inch bed depth.
The total moisture content of coal is the percentage of water in all forms (except water of crystallization of the mineral matter) that resides within the coal matrix. The various forms of moisture in coal are described according to the manner in which they are measured by some prescribed standard method.
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.

ND D 4643 - MICROWAVE METHOD OF DRYING SOILS . Conduct this procedure according to ND D 4643. Consult the current edition of ASTM for procedure in its entirety and equipment specification details. SCOPE . This procedure is used to determine the total moisture content of a soil. The soil is dried to remove all free moisture.
5.2 Moisture can be used in conjunction with the air-dry moisture loss determined by Test Method D3302 to determine total moisture in coal. Total moisture is used for calculating other analytical results to an as-received basis using Practice D3180.
· What are inherent moisture (IM) and total moisture(TM.) in coal? When coal is traded in its specifications two types of moisture values are mentioned. This is very important as it affects the cost of fuel per unit of power generated or per kg of steam produced by the boiler. i.e. it affects the boiler efficiency.

The difference in weight represents the total moisture content of the aggregate. For making batch calculations it is handiest if moisture has been calculated as percent of the SSD weight of the aggregate. The total moisture measured in the test represents both the free moisture and the moisture that the aggregate absorbs.
Dry Basis Moisture Content. Dry basis moisture content (designated M d in the text) is described by the percentage equivalent of the ratio of the weight of water (W W) to the weight of the dry matter (W d).. Note that dry weight moisture content can range from 0 to very large percentages.
The Proximate Analysis of any coal i.e. the % content of Moisture, Ash (A), Volatile Matter (VM), Fixed Carbon (FC) – also Sulphur (S) and Calorific Value (CV) – can be expressed on any of the above bases.
