The waste combustion in the waste bed and the impacts of the waste burning efficiency are complex. In order to solve this problem, the method of numerical simulation has been adopted to simulate waste combustion, and calculate the mass loss rate, moisture evaporation, volatile release, char burning rate. Used the total flow rate of primary air between 50～1 000 Nm3/min to calculate the mass loss, excess air coefficient of waste bed, components of the gas. Calculated results show that the burning efficiency is higher when the total flow rate of primary air is at 517.47～632.09 Nm3/min .
