Abstract
In this study, a thermochemical analysis was conducted to obtain the exhaust composition according to the mixing ratio of hydrogen with methane and a standard city gas. Calculations and analysis of the composition led to the following conclusions. With an increase in the hydrogen mixing ratio, the limit of maldistribution at which a reasonable composition could be obtained decreased, thereby reducing the distribution area of the exhaust composition. In particular, when the distribution heterogeneity increases in the range of 4.22 to 4.86 hydrogen-carbon atomic ratio, the exhaust composition was sensitive to small changes in the hydrogen atom ratio and changed significantly. In addition, regardless of the volume of hydrogen mixed, if the mal-distribution factor is not very large, the generation of hydrogen increased in the theoretical equivalence ratio. Altogether, changes in exhaust composition due to non-uniform distribution can be used as an indicator of actual combustion fluctuations that deviate from ideal combustion.
