Thus, Eq. 1-9 are valid only for mixtures with hydrogen concentrations between 9% and 70%.
Web16 dec. 2024 · Hydrogen has a higher burning velocity and lower minimum ignition energy than ammonia, and therefore is a fuel with less risk of misfiring or unburned compared to ammonia [ 3, 4, 5, 6 ]. On the other hand, hydrogen has a higher flame temperature than ammonia and hydrocarbon fuels, so reducing thermal-NOx is an important challenge [ 7, 8 ]. WebThe laminar burning velocities of hydrogen-air mixtures were reported in the previous studies. Hermanns et al.[9], by using the heat flux method and nitrogen as the diluent, measured the laminar burning velocity of hydrogen-air- diluent mixture at equivalence ratios ranging from 0.7 to 3.1. Other researchers also measured the laminar burn-
Web15 feb. 2024 · Figure 3 presents the normalized sensitivity coefficient of the diluents with respect to the laminar burning velocity of hydrogen and chlorine. When N 2 was used as the diluent, the primary reaction affecting the laminar burning velocity was R2: Cl + H 2 = HCl + H ( Figure 3 a); this reaction generated massive quantities of HCl and H.
