Companies historically develop their branded, typical specification sheet based on the parameters set out above, and in terms of domestic
First, determine the weight of the object while wet. Using a scale, we find the object to be 20g while wet. Next, determine the weight while dry. After drying the object, we weigh it again and find that the weight is 10g. Finally, calculate the moisture content. Using the formula we find the moisture content to be 50%.

The payment to the coal companies are normally made based on the 'As Received' coal properties. 2. As Fired' coal is the coal entering the boiler system. The performance of the boiler and power plant is based on the 'As Fired' coal properties. 3. Air Dried' coal is what is used in the laboratory for analysis.

Common recording standards (in alphabetical order): Airdried basis: Data or results are calculated to the moisture condition of the coal after being allowed to airdry (at room condition humidity). Usually denoted as "ad" or "AD." Asdetermined (airdried) basis: Usually denoted as "adm" or "ADM."
Examples of Equilibrated Moisture in a sentence. The coal sample shall be prepared for its Testing and Analysis for determination of Total moisture (%), Moisture as received basis (%), Moisture air dried basis (%), Equilibrated Moisture (%), Ash% as received basis, Ash% air dried basis, Ash% Equilibrated basis, Gross calorific value (GCV) of coal as received basis, Gross calorific value (GCV ...
Total moisture includes airdry loss moisture and inherent moisture. Airdry loss moisture, which is not linked to organic matter, is the loss of weight resulted by drying at room temperature. Inherent moisture content is determined by heating an airdried coal sample at 105°110°C (221230°F) under specified conditions until a constant ...

India, the world's third largest coal producing country, is expected to maintain strong dependency on coal for the coming few decades. The gross calorific value (GCV) of coal is a key yardstick for many end users purchasing coal from suppliers, as it provides a clear measure of the useful energy content of a coal. Several methods are available to predict GCV using either moisture content and ...
