  • The burning behaviors of Datong coal and char under O2/N2, O2/CO2 and O2/H2O/CO2 atmosphere were comparatively investigated by thermogravimetric analyzer. The influence of CO2 and H2O gasification on the oxy-fuel combustion characteristics of coal and char were mainly studied. The results indicate that at 5% oxygen concentration the burning rate of pulverized coal in each atmosphere decreases in the order of O2/N2, O2/CO2 and O2/H2O/CO2. When the oxygen concentration reduces to 2%, owing to the CO2 and H2O gasification, the overall reaction rate of pulverized coal increases in the same order at high temperatures. The burning rate of char is slower in O2/CO2 than that in O2/N2 at 5% oxygen concentration, but as the burning process is delayed, the overall reaction rate of char in O2/H2O/CO2 rises significantly due to the action of gasification. At 2% oxygen concentration, the overall reaction rate of char in O2/CO2 is higher than the burning rate of char in O2/N2 with the rise in temperature. The overall reaction rate of char in O2/H2O/CO2 further increases because the H2O gasification plays a major role in CO2 and H2O co-gasification. The kinetic analysis shows that at 5% oxygen concentration the apparent activation energy in the atmosphere increases in the order of O2/N2, O2/CO2 and O2/H2O/CO2. However, the apparent activation energy of different atmospheres declines with the decrease of oxygen concentration.
