摘要：

To study the flame stability and NO emission characteristics of lean premixed ammonia/methane turbulent swirling flame, a visual swirling turbulent combustion device was designed and built, and a series of experimental measurements was carried out. The results show that the range of stable combustion of ammonia flame became wider with the increase of equivalence ratio, but when the ammonia mixing ratio was greater than 0.60, the flame oscillated up and down in the chamber and finally blow out; with the increase of equivalence ratio, the NO emission increased; under the same equivalence ratio, NO emission first increased and then decreased with the increase of ammonia mixing ratio. In addition, the chemical reactor network (CRN) method and the one-dimensional laminar flow premixed flame calculation method were used to numerically analyze the corresponding flame states. Although there was a large deviation between the calculated results and the experimental results, the predicted variation trend of NO emission with the ammonia mixing ratio and equivalence ratio was consistent with the experimental results. The sources of the deviation among the three results were analyzed. © 2022 Chemical Industry Press. All rights reserved.
