“…The quantification of the ignition temperature is very important, e.g., for biochar, because it can be directly associated with safety issues during storage and transportation [33]. The occurrences of self-ignition of different biomass-derived fuels or materials are widely documented in the literature, both for non-heat treated biomass, as presented in the works by Schwarzer et al [34], by Castells et al [35], and by Restuccia et al [36], but also for materials resulting from thermochemical conversion processes, such as the approaches presented by Liu et al [37], Zhou et al [38], Restuccia et al [39], Liu et al [40], or Nunes [41]. The latter author even describes a series of incidents that occurred in industrial units to produce torrefied biomass and associated the risk of self-heating and self-ignition with the presence of black particles and the high content of volatiles.…”

The Brazilian sugarcane industry generates a significant amount of waste each year, which should be properly analyzed and studied to allow an adequate recovery and application supported by the best understanding of its properties. The present work reports the ignition and burnout temperatures of sugarcane bagasse (SCB) obtained after performing a thermal analysis using four different heating rates. The intersection method (IM) and deviation method (DM) were employed to approach the ignition and burnout temperatures of the sugarcane bagasse. The ignition temperatures of the SCB measured from IM are between 250 and 263 °C, and their burnout temperatures are between 357 and 377 °C. The ignition temperature was in the range of 205 °C to 236 °C for the DM. IM is recommended for determining the ignition and burnout temperatures. In TGA, the heating rates in the range of 10 °C·min−1 and 15 °C·min−1 are suggested due to their accuracy and the contribution to timesaving in the analysis.
