Knowledge of the fundamentals of dust combustion is necessary for designing safety technologies such as flame arrestors. The structure of flame propagation in a uniformly distributed cloud of volatile fuel particles was simulated. A model based on energy and mass conservation laws was generated. The obtained system of equations was nondimensionalized and solved according to the introduced boundary conditions. Comparison of the results with the existing experimental data in the literature showed remarkable agreement. Finally, the effect of parameters such as particle size and Lewis number on the characteristics of the cloud combustion of biomass microparticles under both lean and rich conditions was studied.
