摘要：

Reducing NOx emissions from industrial burners is a significant concern due to their harmful environmental and human health impact. A computationally efficient numerical model was developed and validated using a detailed GRI 3.0 chemistry mechanism to simulate the combustion process and precisely predict the NOx emissions from industrial burners. The numerical model was implemented to reduce NOx emissions by varying the burner's primary to secondary air mass flow ratio. An optimum nozzle diameter was proposed to abate NOx emissions by a factor of 0.845. A feasibility study on the optimised burner was conducted by blending up to 50% hydrogen by volume with natural gas by maintaining the same burner power output. Results showed that the burner exhibited similar flame characteristics until 40% hydrogen was added to natural gas. A 41.8% in-crease in NO and a 76.8% decrease in CO emissions were observed by enriching natural gas with 50% hydrogen.(c) 2023 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
