Description
DIN A2 grade wood pellets are a type of biomass fuel made from compressed wood or other organic materials. They are specifically classified under the **DINplus or ENplus** standards, which ensure the pellets meet specific quality criteria for use in heating systems.
### Key Features of DIN A2 Grade Wood Pellets:
1. **Raw Material**: Made from wood with a higher bark content than A1 grade, such as industrial by-products or recycled wood.
2. **Ash Content**: Higher than DIN A1 pellets, typically ranging between **0.7% and 1.5%**.
3. **Calorific Value**: Similar to A1 grade, providing sufficient energy for heating, typically around **16.5-18 MJ/kg**.
4. **Applications**:
– Suitable for larger, industrial heating systems or boilers with robust cleaning mechanisms.
– Not recommended for small residential stoves due to higher ash and potential emissions.
5. **Moisture Content**: Low, generally below **10%**, ensuring efficient combustion.
6. **Durability**: Produced with strict mechanical durability to ensure minimal dust production.
### Comparison with DIN A1 Grade:
| Feature | DIN A1 Grade | DIN A2 Grade |
|———————|————————-|————————|
| **Ash Content** | ≤ 0.7% | 0.7%-1.5% |
| **Applications** | Residential stoves | Industrial heating |
| **Raw Material** | Pure, low-bark wood | Higher bark content |
DIN A2 grade wood pellets are an economical choice for larger systems where the slightly lower quality is acceptable due to cost savings and robust emission handling. Always ensure your heating system is compatible with this grade before use.
