In this research, the influence on natural gas combustion of H2 and CO was investigated by numerical calculations with elementary reactions. The investigation was carried out using the following procedures: 1. To research basic oxidation characteristics of CH_4/H_2/CO mixed fuel, parametric calculations for initial temperature were carried out. 2. For investigation of the effect of H_2 and CO on CH_4 combustion, the calculations with H_2 and CO initial mole fraction variation was carried out. As a result, it was clarified that the oxidation temperature of CO was higher than that of CH_4 and H_2, the increase of H2 initial fraction has the effect to advance CH_4 ignition tuning, and increase of the CO fraction, under the condition that only CO was added, has the opposite effect of H_2 addition.
