Humidified Cracked NH3 emissions data

Using renewably produced ammonia as a zero-carbon fuel is gaining momentum due to its ease of transportation and storage as a hydrogen vector. This is particularly true for partially cracking ammonia immediately prior to use, injecting a blend of NH₃, H₂ and N₂. Challenges with this fuel combination relate to the emissions of NOx and unburned NH₃, as well as understanding flame stability for practical applications. In this study, a 20 %_(vol.) cracked ammonia blend was investigated using a fully premixed swirl burner, operating at a thermal power of 10 kW with steam injection of 30 %_(vol.) of the fuel and preheating inlet temperatures of up to 390 K, for a range of equivalence ratios from lean to rich. Emissions of NO, NO₂, N₂O, NH₃, H₂, O₂ and H₂O were recorded. The emissions data of NO, NO₂, N₂O, NH₃ and H₂ is is available in a .xlsx file as both ng/J and ppmv, dry 15% O₂ for a range of equivalence ratios across the four different cases examined. The first dataset is emissions on a ng/J basis in the format of equivalence ratio (a.u.) in column A, with the corresponding ng/J emissions value for each of the four cases in columns B, C, D and E (ng/J). Rows 4 to 15 cover NO emissions, 17 to 28 cover NO₂ emissions, 30 to 41 cover N₂O emissions, 43 to 54 cover NH₃ emissions and 56 to 67 cover H₂ emissions. Column G repeats the same data as column A (equivalence ratio - a.u.) and columns H to K show the corresponding error bar values in each direction for the emissions values (ng/J) in columns B to E. Finally, this dataset is repeated in an identical format in columns O to Y, but this time the emissions values are in the units ppmv, dry 15% O₂. <br>
