Abstract: The main purpose of this study was the optimization of torrefaction conditions for biochar cofiring with new Taguchi indicators. However, the combustion characteristics of biochar cofiring in different furnaces and reactors are distinct. Examining optimal torrefaction conditions using the Taguchi method based on maximum energy or mass yields is paradoxical. Accordingly, three indicators, that is S index, proximate-based index (PA index), and elemental-based index (EB index), were proposed for solid fuel combustion. To study the combustion behavior of biochar torrefied under optimal conditions, a single pellet combustor was employed to record the characteristic time and gas emission at various reaction regions. Furthermore, the effects of ambient temperature and biomass blending ratio (BBR) on combustion behavior were investigated in the single pellet combustion experiment.
