摘要：

To reduce the harmful emissions from energy generation efficient use of the available sources of fuel is vital. In this current work hydrogen dilution with methane, ethanol, and ammonia is considered to comparatively study the effect of these fuel blend on combustion characteristics. Each of these fuels are potential sources of energy with certain limitations either in efficiency or emission quality. The mixture composition of 2080, 50-50, and 90-10 percent hydrogen with methane, ethanol, and ammonia is considered for the comparison. Laminar burning speed (LBS), and ignition delay time (IDT) are calculated numerically for the comparative analysis of these three fuel blends. To predict the influence of hydrogen on emission quality, change of species concentration with temperature is calculated. The IDT is calculated at stoichiometric condition, 1100-1900 K temperature and 10 atm pressure. The initial temperature of 400 K and 0.6 to 1.4 equivalence ratio is used for LBS calculations. With the help of sensitivity analysis, the effect of mixture on important reaction is studied. The concentration changes of CO, CO2, NO, and NO2 is compared between various hydrogen blends of different fuel.
