dc.description.abstract | Downward propagation of a combustion front in a packed bed of wood particles, with air supply from below, is examined theoretically and experimentally. Using a single-step reaction, with a kinetic model of char oxidation as the dominant mechanism, and assuming local thermal equilibrium, but allowing a local chemical nonequilibrium between the solid and gas phases, the front speed uF, the adiabatic temperature Tr, and the extent of solid consumption rs/ns are determined as functions of the entering air pole-velocity u>ng. Both oxygen-limited and fuel-limited regimes, with the boundary marked by the stoichiometric burning, are examined. In the oxygen-limited regime, Tr, uF, rs/ns, and the thickness of the front [delta]F all increase with u>ng. In the fuel-limited regime, the reverse occurs and the extinction at high u>ng is predicted. In the oxygen-limited regime, where the bed is not yet fluidized, the experimental results are in good agreement with the predictions. | en_US |
