A mechanism for the oxidation and fragmentation of a char particle was developed. Qualitative agreement between the model simulations and experimental data observed in the literature, is found for the higher gas temperatures (1700K). However fundamental differences are found in the particle temperature histories and burnout times at low temperature (1250K). The role that fragmentation plays on the char particle history is incorporated into the model and the possible production of fine particulate through fragmentation is examined. A relatively large fraction of the mass of char available for fragmentation is produced early in the combustion history of the particle. Therefore, if this mechanism is important in the generation of fine particulate matter during char combustion, the simulations indicate that it would occur early in the combustion process. Due to the limited experimental data in the literature on the time resolved particle size distribution in the early stages of combustion, corroboration between model and experiment was not possible.
