Recently, ammonia (NH3) is attracting attention as a promising hydrogen energy carrier and as a carbonfree fuel in NH3 direct combustion. It is important to know combustion characteristics of NH3 and to develop accurate NH3 reaction mechanism. In the present study, flame characteristics of NH3/air and NH3/N2O mixtures and ignition characteristics of a NH3/N2O/Ar mixture were investigated. N2O was considered here because of an important intermediate in NH3 combustion. The ignition characteristics of a NH3/N2O/Ar mixture were investigated using a micro flow reactor with a controlled temperature profile and a quadrupole mass spectrometer. Numerical predictions computed with the NH3 chemical reaction mechanism were compared with the experimental data obtained from the present experiments and literature.
