The refined model of ignition methane – air and reactive iron particle mixture that takes into account the kinetics of particles oxide film growth is developed. Comparison of the ignition delay times in methane-air-particles mixture obtained in the calculation of the proposed model with experimental data showed their satisfactory agreement in the range of temperatures 900–1200 K and pressures 1–1.2 MPa. At low exposure temperatures the new model describes the ignition delay time more accurately than our model constructed earlier.

Keywords:
methane – air mixture, ignition delay time, reactive metal particles, detailed chemical kinetics, mathematic modeling.
