Coal Quality Discussion & Documentation Support
Coal quality should be discussed before dispatch, not after a dispute. We align product basis, test basis, sampling method and documentation expectations before the order is finalised.
Parameters
What Buyers Should Review
| Parameter | Meaning | Buyer Impact |
|---|---|---|
| GCV | Gross Calorific Value; heat content on a specified basis. | Useful energy and cost comparison. |
| Moisture | Water content, depending on test basis. | High moisture reduces effective heat and affects handling. |
| Ash | Non-combustible residue after burning. | Disposal, residue and operating cost. |
| Volatile matter | Combustible gases released during heating. | Combustion behaviour. |
| Sulphur | Sulphur content of coal. | Emissions and application suitability. |
| Size distribution | Coal particle size range. | Handling, feeding and burning. |
