| Ash Content | <9 | 4-8 |
| Volatile Matter | 38-42 | 39-41 |
| Fixed Carbon | 40-42 | 40-42 |
| Calorific Value (adb kca/kg) | 5,800-6,400 | 5,800-6,400 |
| Total Sulfur | <1.0 | <1.0 |
| Handgrove Grindability Index | ±45 | ±45 |
| Ash Fusion Temperature (Reduced Atmosphere) | MSJ | SBB |
|---|---|---|
| Initial Deformation | Over 1,250°C | Over 1,250°C |
| Hemisphere | Over 1,250°C | Over 1,250°C |
