Combustion of Premixed Organic Dust Particles in Inert Porous Media (Two-temperature model

In this paper, the combustion of premixed micro-sized organic particles in an inert porous media is studied by applying a two-temperature model in a semi-infinite canal for both lean and rich mixture conditions. By solving equations analytically, including energy and mass conservation, in all three pre-heat, reaction and post-flame zones, the distribution of temperature and mass fraction for various Lewis number, equivalence ratio, porosity and particle size are obtained. It is observed that super-adiabatic combustion wave occurs for lean and rich mixture conditions, while subadiabatic combustion wave occurs for mixture with average equivalence ratios
