AB - The volatile matters in biomass have an essential effect on their ignition  stabilization. In the present work, the homogeneous ignition of seven kinds  of biomass and eight kinds of coals is studied by the pulse ignition  technique. At ignition, the flame brightness of biomass appears more faintly  than that of coal. The flame color appears in bluish violet for biomass and  yellowish red for coal. The homogeneous ignition temperature ranges from  270°C to 310°C for biomass and 390-500°C for coal, respectively, and it  decreases with the decrease of the particle size. A theoretical model is  established to predict the homogeneous ignition temperature by the thermal  balance method and the thermal explosion theory. Based on the theoretical  prediction, a quasi-linear model and a non-linear model are developed  through the least square algorithm.
