SUMMARY:Numerical modeling of hydrogen staged combustion to mitigate NOx
DESCRIPTION:Decarburization of the steel industry emission gases have led to extensive research into the use of hydrogen as a fuel source in many of their operations. Research has shown that burning hydrogen fuel in a reheating furnace may cause higher NOx levels in the flue gases which can be harmful to the environment. Several techniques have been studied to mitigate this effect including staging the hydrogen combustion. This work modeled the application of hydrogen fuel using the staged combustion approach with a robust computational fluid dynamics (CFD) model to investigate the potential to reduce NOx emission. Three scenarios were considered for the investigation. Results from the study show that staging the hydrogen combustion reduced the NOx emissions.  However, the average temperature of the furnace was also seen to slightly drop. Staging 17.5% of the combustion air showed the best result with a NOx reduction of 14.5%.
