Abstract: Coal reverse filtration combustion involves clean coal combustion, pollutant and disaster prevention and control. In-depth study of reverse filtration combustion wave model is of great significance for China to achieve carbon neutrality and sustainable development. In-depth study of the reverse filtration combustion wave model is of great significance for China to achieve the goal of carbon neutrality and sustainable development. However, there are still several key problems to be solved in this model : ① The traditional oxygen component transport equation is difficult to solve the problem of oxygen non-equilibrium between gas and solid phases. ② There is a lack of in-depth analysis of the dynamics and oxygen supply control mechanism of the reverse propagation dynamic process of filtration combustion wave. Based on this, a numerical model of reverse filtration combustion wave including five-step reaction system is constructed. At the same time, two different coal samples （ bituminous coal CC and anthracite XA ） were used to study the reverse filtration combustion under different flow conditions （8, 32, 64 L/min ）. The results show that : The model is in good agreement with the experiments, and it successfully predicts the propagation process of reverse filtration combustion wave. As the flow rate decreases, the reduction in oxygen supply leads to reduced reactivity, resulting in a decrease in both peak temperature and propagation rate. At the same time, the peak temperature is also affected by the type of coal sample. Under the same flow condition, the temperature of XA coal sample is lower than that of CC coal sample. As the reaction temperature increases, the reaction rate accelerates, and the limiting conditions of reverse filtration combustion from kinetic mechanism to oxygen transport mechanism.
