Abstract

he Oxy-fuel combustion of Yunfu bituminous (YFB) chars was studied by isothermal thermogravimetric experiments at 1273K-1573K. The surface area of coal chars prepared at different stages of Oxy-fuel combustion was determined by BET methods. The pyrolysis temperature leads to a slight increase in the average pore diameter and surface area, and the average pore diameter of YFB increases with increasing carbon conversion. Pore structure parameters were calculated by random pore model. Compared to the experimental data, it is found that the random pore model has good ability to depict the reactivity of coal chars Oxy-fuel combustion under high temperature, indicating the random pore model was used to depict the reactivity of coal char combustion in Oxy-fuel.
