Our smelting-grade coal is rigorously tested consistently delivers the following properties, making it a reliable high-value feedstock:
| Specification | Code | Typical Range / Value | Importance for Smelters |
|---|---|---|---|
| Volatile Matter | Rb1 | 22 – 28% | Crucial for efficient combustion stable flame temperature. |
| Ash Content | Rb3 | 10 – 13% | Directly impacts furnace efficiency slag hling. |
| Calorific Value (Air-Dried Basis) | CV24 | 6,100 – 6,300 kcal/kg | The primary measure of energy content per unit weight. |
| Calorific Value (As Received) | CV25 | 5,800 – 6,100 kcal/kg | Reflects true energy content with inherent moisture, key for pricing. |
| Calorific Value (Dry Basis) | CV26 | 6,400 – 6,600 kcal/kg | Theoretical maximum energy content, useful for comparison. |
| Calorific Value (Ash & Moisture Free) | CV27 | 7,600 – 7,900 kcal/kg | Indicates the pure energy potential of the coal’s carbon content. |
Note: Specifications are based on typical analysis. Certified Batch Analysis Sheets are provided with each shipment.
Why Smelters Choose Moss Agate Coal: The Technical Advantage
Understing these specifications is key to optimizing your smelting process. Here’s a breakdown of why each property matters:
1. Optimal Volatile Matter (Rb1: 22-28%)
Volatile matter refers to the gases released when coal is heated. A level between 22-28% is ideal for smelting because:
- Stable Combustion: It ensures a rapid ignition a long, stable flame, providing consistent heat distribution throughout the furnace.
- Efficient Burn-Out: This range allows for complete combustion of volatiles before the coal becomes coke, maximizing energy release minimizing unburnt particles that can affect metal purity.
2. Controlled Ash Content (Rb3: 10-13%)
Ash is the non-combustible mineral residue left after burning. Our controlled ash content is a significant advantage:
- Reduced Slag Volume: Lower ash means less slag production. This decreases the energy required to melt the slag reduces the frequency of furnace tapping for slag removal, increasing operational uptime.
- Lower Flux Consumption: Smelters often need to add fluxes (like limestone) to manage slag chemistry. Less inherent ash simplifies slag chemistry can reduce flux costs.
- Improved Furnace Efficiency: High ash can act as an insulator, reducing heat transfer to the charge. Our lower ash content promotes efficient heat transfer to the raw materials.
3. High & Consistent Calorific Value (CV24-CV27)
This is the most critical factor—the amount of energy released per kilogram of coal. Moss Agate’s high CV provides:
- Maximum Energy Output: A higher CV means you need less coal to achieve the same melting temperature, improving fuel efficiency reducing hling costs.
- Predictable Operations: Consistency in CV is as important as the value itself. Our coal’s predictable energy output allows smelters to fine-tune their feed rates for optimal consistent metal quality.
- Cost-Effectiveness: When priced on a cost-per-calorie basis (as is industry stard), our high CV coal delivers superior value, directly translating to lower cost per ton of metal produced.
