Frequently asked questions & answers.
What are torrefied wood pellets?
Torrefied pellets are a clean and renewable, drop-in replacement for coal. They represent an environmentally friendly coal substitute reducing Green House Gases (GHG’s).
Why use torrefied wood pellets?
- Easily integrates into existing systems without major changes or expensive conversion.
- Higher energy density; energy content similar to coal.
- Can be co-fired in any proportions or replace coal completely.
- Superior energy density, reducing supply chain and logistics costs by 25%-30%.
- Torrefied wood pellets are water resistant allowing them to be stored outside where they can withstand the elements.
How do you make torrefied wood pellets?
- Receiving & Storage: Woods chips are collected and stored.
- Drying & Grinding: The wood chips are dried by the residual heat from the torrefaction process.
- Torrefaction: The ground and dried wood fibre is heated in the absence of oxygen (torrefaction).
- Pelletizing: The resulting charcoal-like substance, also called biocoal, is pressed into a pellet.
