• Papers reported in the 7th International Symposium on "Novel Carbon Resource Sciences" Jun. 23-24, 2011Thermogravimetry (TG) for two different coal ranks, Loy Yang coal and Newlands coal, was carried out in an atmospheric air environment. Detailed parameters of the heterogeneous oxidation reaction for each coal rank were estimated by analyzing the TG results. Heat and mass transfer of a single pulverized coal particle that was heated at a constant temperature were numerically simulated. In this calculation, the decrease in the mass ratio caused by the oxidation reaction was considered. The numerically analyzed results were compared and the influence of particle parameters (coal rank, initial particle diameter, oxygen concentration) on burn-off time was examined.
