To estimate the nature of combustion ethane-air mixtures the kinetic criterion of steady-state condition has been created and tested using algorithm PREMIX from CHEMKIN package. The process is fully branched inside the flammability region and increasing or decreasing equivalence ratio cause reduction of flame temperature as well as the rate of each elementary reaction. Nearby flammability limits criterion used points to steady-state conditions, i.e. chain carriers reach their steady-state, small concentrations. Hence, even small outer impulse can break chains branching and stop flame propagation.
