Abstract
A model designed for the prediction of heat and mass transfer effects in the boundary layer of a reacting coal particle was extended to analyse the trends as the pressure is increased well above atmospheric conditions. The oxidation of volatile species in the boundary layer is based on a two step mechanism where the dependence of the flame speed on pressure is accounted for. The model was able to particle temperature in a range of gas composition and pressure as well as fuel type.
