英文摘要Recently, ammonia/methane mixtures have been considered as potential alternative fuels. The present study experimentally investigates the blow-off limits, flame structure, and pollutant emission of ammonia/methane mixtures in a partially premixed swirl-stabilized burner. The effects of fuel composition and the equivalence ratio are also studied. The results show that the NH3/CH4 flame can be stabilized at an equivalence ratio of 0.55. The addition of methane has a positive effect on the blow-off limits. For the chemiluminescence profile, the OH* distribution and CH* distribution of NH3/CH4 flames show a similar tendency under various conditions. The peak OH* and CH* radiances monotonically decrease with increasing ENH3, while the maximum NH2* shows an opposite trend. The influence of the equivalence ratio on OH* and CH* in the NH3/CH4 flames is negligible. However, when ENH3 is 60%, the equivalence ratio has a significant effect on NH2*. In terms of pollutant emissions, the peaks of NO and NO2 emissions are all found around an ENH3 of 20%. When the equivalence ratio reaches 1.0, NO and NO2 emissions are as low as 15 and 10 mg/m3, respectively. At the same time, both CO and unburned NH3 emissions increase. Therefore, further studies on the application of secondary air or improvement of the fuel injection method to improve the combustion efficiency and reduce the pollutant emissions for ammonia combustion are still needed.
