Abstract

Ignition and burnout of a single biomass particle were studied numerically. A one-dimensional particle combustion model was developed which is capable to simulate all the intraparticle conversion processes (drying, recondensation, devolatilization, char gasification/oxidation and heat/mass/momentum transfer) to investigate the conversion and ignition process of single biomass particle. The results indicated that the ignition occurrs homogeneously in all cases. Also the results showed that the homogeneous ignition delay was very sensitive to particle size and shape but the effects of oxygen concentration were not very significant. The influences of these factors on particle burnout were much more remarkable than ignition behaviour.
