Utilization of biomasses, such as woody biomass and torrefied biomass, in pulverized coal thermal power plants is important for reducing CO2 emissions. However, these biomasses have the risk of ignition during pulverization in roller mill. In this study, the propensity for self-heating of deposited biomasses and coals in roller mill was evaluated by the wire-mesh basket tests. The results showed that initial rate of heat release had good correlation with maximum temperature rise. Thus, the initial rate of heat release is considered suitable for evaluating the self-heating characteristics of biomasses and coals. It was clarified that the initial rates of heat release of biomasses were lower than those of coals.
