Numerical simulation and synergistic NOx reduction of preheated combustion in a 660 MW tangential-fired boiler under variable loads

Key Points

• Synergistic NOx reduction is achieved through numerical simulation in a tangential-fired boiler, indicating a potential for improved emissions control.
• The boiler operates efficiently under variable loads, demonstrating a reduction in nitrogen oxides by optimizing preheated combustion processes.
• Numerical simulation methods reveal how combustion changes with temperature variations, allowing for targeted interventions in emission reduction.
• Impacts on air quality may improve due to the effective management of NOx emissions, suggesting further evaluation in diverse operational contexts.
