For the reduction of CO₂ emissions from pulverized coal power plants, utilization of biomass, such as wood pellet, is expected. However, there are some risks of self-heating and ignition of coal and biomass deposits in roller mill. In this study, effects of ambient temperature and biomass/coal ratio on self-heating propensities of biomass/coal deposits were evaluated by the wire-mesh basket tests. The results showed that the initial heat release rate of coal was affected by ambient temperature much more than biomass. Furthermore, the initial heat release rate of mixture was decreased with the increase of the ratio of biomass to coal.
