Optimizing thermal performances and NOx emission in a premixed ammonia-hydrogen blended meso-scale combustor for thermophotovoltaic applications

International Journal of Hydrogen Energy, Journal Year: 2023, Volume and Issue: 48(77), P. 30191 - 30204

Published: May 3, 2023

As a carbon-free energy carrier, ammonia has attracted significant interest in the combustion field as potential substitute for fossil fuels. However, focus been given to application at meso-scale conditions, particularly with regard thermal performance and NOx emissions. Therefore, present study numerically investigates 3-dimensional time-domain premixed ammonia/oxygen combustor optimize its' emission power generation applications. The numerical model is firstly validated by using experimental data available literature. Then, effects of 1) inlet pressure (Pin), 2) equivalence ratio, 3) hydrogen blended ratio on temperature uniformity, outer wall mean (OWMT), NO emission, exergy efficiency are examined. results indicate that increasing Pin intensifies mixing process mixture gases, thus reducing residence time high-temperature flame chamber. optimized OWMT emissions up 26% 40.3% respectively, only 9% compensation standard deviation achieved, when velocity set 0.5 m/s 3.0 bar. Furthermore, varying range 0.95–1.1 minor influence improving performances, but impact mitigating performance. Additionally, blending less than 15% reduction maximum (up 53%); however, can be neglected. Further analysis reveals elevating decrease due increased exergy. In general, this work provides preliminary method an ammonia/hydrogen-oxygen-fueled purpose.
