The gradation of non-coking coal is based on Gross Calorific Value (GCV), the gradation of coking coal is based on ash content and for semi coking /weakly coking coal it is based on ash plus moisture content, as in vogue as per notification. Grades of Coking Coal. Grade. Ash Content. Steel Grade - I. Not exceeding 15%.

Moisture content is an important parameter in coal analysis. It is needed for determining the calorific (heating) value and handling properties of a coal. The moisture value given for a proximate analysis is the moisture measured as mass lost from a sample under specified conditions after heating in a moisture oven to 104 to 110°C (ASTM …

Recommended practices in coal crushing are: (1) incorporation of a screen to separate fines and small particles to avoid extra fine generation in crushing, and (2) …

Coal Specifications. We exclusively trade thermal coal of Indonesian origin and offer three main calorific values – GAR 4200 kcal/kg, NAR 4700 kcal/kg and NAR 5500 kcal/kg. The table below indicates the typical specifications of each category of coal under the American Society for Testing and Materials Standard. Specification in ASTM Standard.

Measuring volatile matter in coal and recording standards for different components of the volatile matter. Prior to testing, moisture content is driven off and …

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.

The Funding Opportunity Announcement is anticipated to be issued in March 2020.
