In order to analyze the complex chemical dynamics mechanism systematically, check out redundant species and reactions, and improve computational efficiency, a numerical platform for detailed mechanism analysis and simplification was established. Path flux analysis, sensitivity analysis and reaction rate analysis were comprehensively used to analyze and reduce a detailed mechanism, which can be applied to the study of the flame inhibited by phosphorus-containing compounds(PCCs). Under this platform, the important information about species and reactions were obtained. Compared with the size of the detailed mechanism which consists of 121 species and 682 elementary reactions, that of the reduced mechanism is relatively small, with only 46 species and 183 reactions. In the case of C3H8/DMMP/air premix flame, the reduced mechanism can improve the computational efficiency by 9.47 times and keep good calculation precision.
