NOx emissions were reduced by about 5.5% when the burners were tilted downward by 15° which be attributed to two factors, namely the relatively insignificant contribution of thermal NOx mechanism in utility boilers and the role of NOx reburning in reducing conditions. The temperature of the exit gas was reduced by 33 K due to the downward tilt. The results suggest that a downward tilt of the burner (− 15°) has a significant effect on the particle trajectories and the residence time of the particle in the high temperature burner zone. The effect of burner tilt was investigated by analyzing the effect on gas flow, temperature distribution, coal particle trajectories and NOx emissions. Computational fluid dynamics (CFD) simulations were performed on a 210 MWe tangentially fired pulverized coal boiler to understand the impact of two vertical burner tilt angles, − 15° and + 15°. The current work seeks to obtain a detailed understanding of the effect of burner tilt on the flow and heat transfer inside the boiler by utilizing numerical simulations. One of the principal ways of finding a compromise in tangentially fired pulverized coal (PC) boilers, which constitute the majority of the utility boilers, is through tilting the burners. High gas temperatures inside the boiler may also lead to slagging and fouling problems, which adversely affect the heat transfer to the steam side. Steam generation requires high gas temperatures, which often lead to high NOx emissions.

Understanding of the flow field and heat transfer in a boiler is important to meet with the often-conflicting objectives of efficient steam generation, safe operation and minimization of pollutant emissions.
