In this paper, the cement production pulverized coal combustion characteristics experiment was done respectively at 21%, 30%, 35%, 40% and 100% oxygen concentration, on this basis, the pulverized coal combustion kinetic parameters of different oxygen concentration was calculated based on the different reaction mechanism of integration of different functions.The results showed that: with the increase of oxygen concentration, pulverized coal combustion Thermal Gravity(TG) curves moved to lower temperature zone, the maximum burning rate increased, and the ignition and burnout temperature significantly decreased, which caused ignition and combustion of pulverized coal relatively easy.The control steps of coal combustion were probably chemical reaction., and with the increase of oxygen concentration, activation energy and pre-exponential factor increased.
