The combustion of a carbon particle under control of both chemical kinetic and intraparticle diffusion is analyzed. Percolative fragmentation is taken into account to express carbon combustion efficiency. Continuous and discrete models are considered and their advantages and drawbacks examined. A combustion model that couples features of continuous and of discrete models is proposed. Results and example calculations are presented.

A simulation model of char oxidation is introduced in which char particles are represented by randomly generated clusters of bonds on a lattice. Realizations are generated by means of a percolation algorithm. Bonds in contact with the ambience burn at a mean rate which depends on cluster size. By ad
