RI 5668 Thermodynamic Properties Of The Combustion Products Of Graphite And Oxygen In Idealized Dust Flames ? Introduction And Summary

Computation of the thermodynamic properties of the reaction products in the deflagration of explosive gas mixtures has been a most valuable guide regarding the possible kinetic mechanisms of homogeneous combustion processes. Knowledge of the physically possible end states is indispensable for understanding observed deviations from equilibrium in heterogeneous combustion. However such information on dust flames is entirely lacking. To complement a Federal Bureau of Mines study of stationary graphite dust flames burning in pure oxygen,6/ this report gives examples, at atmospheric pressure and room temperature, of composition profiles in an idealized oxygen-dust flame, with both mass and enthalpy being preserved. Similar profiles can be obtained from the data of the paper for elevated temperature and pressure.
