Abstract
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.
