In this study, the combustion properties of torrefied wood pellets (hyper wood pellets) were evaluated using a cone calorimeter, and instrument typically used to verify the fireproof performance of architectural materials. it can estimate various combustion parameters, e.g., transition changes in the heat release rate, weight decrease during the burning process, ignition time, flameout and burnout time, and combustion heat, in a single experimental run with no further grinding of the sample required. In the case of torrefied pellets from Japanese cedar softwood (Sugi, Cryptomeria japonica), there was no significant delay in ignition time compared with that of the non-torrefied pellets. however, smaller heat release values for flaming combustion and a longer burnout time were observed for pellets with a higher torrefaction temperature.
