英文摘要	this paper evaluates the potential of hydrogen (h-2) and ammonia (nh3) as carbon-free fuels. the combustion characteristics and nox formation in the combustion of h-2 and nh3 at different air-fuel equivalence ratios and initial h-2 concentrations in the fuel gas were experimentally studied. nh3 burning velocity improved because of increased amounts of h-2 atom in flame with the addition of h-2. nh3 burning velocity could be moderately improved and could be applied to the commercial gas engine together with h-2 as fuels. h-2 has an accelerant role in h-2-nh3-air combustion, whereas nh3 has a major effect on the maximum burning velocity of h-2-nh3-air. in addition, fuel-nox has a dominant role and thermal-nox has a negligible role in h-2-nh3-air combustion. thermal-nox decreases in h-2-nh3-air combustion compared with pure h-2-air combustion. nox concentration reaches its maximum at stoichiometric combustion. furthermore, h-2 is detected at an air-fuel equivalence ratio of 1.00 for the decomposition of nh3 in flame. hence, the stoichiometric combustion of h-2 and nh3 should be carefully considered in the practical utilization of h-2 and nh3 as fuels. h-2 as fuel for improving burning performance with moderate burning velocity and nox emission enables the utilization of h-2 and nh3 as promising fuels. copyright (c) 2014 john wiley & sons, ltd.
