A simple one-dimensional calculation of char burnout was conducted to show the effect of CO₂ gasification reactivity on the total char burnout under oxy-combustion environment. A global char burnout model considering the influence of pore diffusion, chemical reaction and mass transfer and a double-film model was used. The apparent activation energy for char-CO₂ reaction was determined reasonably from the literature and the apparent pre-exponential factor was changed based on the relative rate of CO₂ gasification to oxidation. When the char-CO₂ reaction was included in the calculation of 1600K condition, the char burnout was improved by 1.1% in the case of low reactivity and by 9.1% in the case of high reactivity, relative to the char-O₂ only case. Also, this CO₂ gasification effect on the char burnout was increased at high temperature because of the activation of the char-CO₂ reaction.
