OPTIMAL DESIGN OF HOMOGENEOUS IGNITION OF BIOMASS BY PULSE IGNITION TECHNIQUE

ABSTRACT
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.
