TL Biomass Technology JSc., is a pioneering Vietnamese enterprise in the field of sustainable forestry and biomass energy. With a commitment to green growth, innovation, and international standards, TL Biomass provides eco-friendly fuel alternatives that contribute to carbon neutrality and energy efficiency worldwide.
Black wood pellets (also known as torrefied pellets) are advanced biofuels produced by heating biomass (usually wood) in a low-oxygen environment. This process increases energy density, water resistance, and durability.
What Are Black Wood Pellets?
Black wood pellets are advanced biofuels made from torrefied biomass—wood that has been heated in a low-oxygen environment to remove moisture and volatile compounds. The result is a dark, carbon-rich pellet with improved energy density and performance.
- They are often used as a coal substitute in power generation due to:
- Higher calorific value
- Better grindability
- Water resistance
Other names: Torrefied pellets, advanced biomass pellets, bio-coal
Key Physical Properties
| Property | Value |
|---|---|
| Color | Dark brown to black |
| Calorific value | 18–22 MJ/kg (higher than white pellets) |
| Moisture content | <5% |
| Bulk density | ~750–850 kg/m³ |
| Ash content | 1–3% (depending on feedstock) |
| Hydrophobicity | High – resistant to water |
| Grindability | Similar to coal |
Applications
| Sector | Use Case |
|---|---|
| Power Generation | Co-firing or full replacement for coal |
| Industrial Heat | Cement, steel, and paper industries |
| Biochar/Carbon | Source of bio-based carbon for special applications |
