Exothermic reaction of coals and biomass fuels during low-temperature oxidation causes self-heating and spontaneous combustion of them. In this study, increases in temperature due to low temperature oxidation were measured for 7 kinds of coals by using an adiabatic heating reactor. Simultaneously, oxygen concentration of off-gas from the reactor was measured to estimate the amount of oxygen consumption. As a result, it was found that the exothermic amount per unit oxygen consumption is approximately constant for all coals examined in this study. This constant will be useful for prediction of exothermic property of these fuels.
