【 摘 要 】

Torrefaction is a mild heat treatment that improves hydrophobicity, durability, and grindability of wood. In combination with pelletization, torrefaction maximizes energy density. Although the usage of torrefied fuel has been mainly aimed at large-scale power generation, small-scale decentralized heat utilization has benefit of easier supply with raw materials from local communities. In this study, for the small-scale use of torrefied pellets in the local communities, a combustion test using a small cooking stove was carried out. In comparison with normal wood pellets, both pellets burned with flame, and no significant difference was observed in their ignition. Given the longer non-flame combustion period of torrefied pellets than normal pellets, the combustion chamber was kept hot for a longer period. Although torrefied fuel has been assumed for large-scale power generation, it can be possibly utilized as a convenient fuel for cooking and heating in the local communities with advantage in storage and handling.
