Economical Biomass Solution

Biomass can be an important energy source.  However, nature provides a large diversity of biomass with varying characteristics. To create highly efficient biomass-to-energy chains, torrefaction of biomass in combination with densification (pelletisation or briquetting) is a promising step to overcome logistic economics in large-scale sustainable energy solutions, i.e. make it easier to transport and store it. Pellets or briquettes are lighter, drier and stable in storage as opposed to the biomass they are made from.

Torrefaction of biomass, e.g., wood or grain, is a mild form of pyrolysis at temperatures typically between 200 and 320 °C. Torrefaction changes biomass properties to provide a much better fuel quality for combustion and gasification applications. Torrefaction leads to a dry product with no biological activity like rotting.

Advantages of Torrefied biomass:

• Higher Energy Density
• More Homogeneous Composition
• Hydrophobic Behavior (Repels Water, Store Outside)
• Elimination of Biological Activity
• Improved Grindability (Better Co-Firing Properties)
• Stablized Fuel Storage
