Abstract

A model has been developed for a description of steady, laminar flames in coal dust-air mixtures, which includes radiative transport, a two-phase energy equation, and the heterogeneous carbon gasification of the coal particles. The equations were numerically integrated and predictions of flame structure and the adiabatic flame speed are presented. The predicted speed agrees well with experiments carried out in a burner with heated walls. The effect of coal particle size upon the resultant adiabatic flame speed is presented as a function of the heterogeneous combustion rate.
