| Outline of Final Research Achievements |
The risk of dust explosion of woody biomass was evaluated according to JIS Z8818. The comparison of the wood dusts in different species, the tendency of higher risk of dust explosion was observed in the species of higher board density. As the effect of extractives in wood, the sticky in softwoods acted to reduce the risk, and the ignitability in hardwoods acted to increase. Furthermore, a small amount of woody biomass mixed with coal or charcoal caused to raise the risk of dust explosion. On the other hand, the torrefaction treatment enhanced the minimum ignition energy of the wood pellets and reduced the risk of dust explosion.
