Organic dust flames deal with a field of science in which many complicated phenomena like pyrolysis or devolatization of solid particles and the combustion of volatile and char particles take place. One-dimensional flame propagation in the cloud of a fuel mixture has been analyzed, in which the flame structure is divided into three zones: Preheat zone, reaction zone and post flame zone. It is assumed that particles pyrolyze first to yield a fuel mixture consisting of gaseous and charry fuel. In this research, the effect of char content on the pyrolysis process has been taken into account and a novel non-linear burning velocity correlation is obtained. Our results are in reasonable agreement with experimental data.
