摘要
A study of the emission characteristics of reheating furnaces shows that NOx emissions can be steadily controlled through operational regulations such as adjusting the air-to-fuel ratio, maintaining adequate furnace pressure and biasing the combustion environment in the furnaces. Experimental results demonstrate that flue gas recirculation can be used to reduce NOx formation when the emission standard cannot be met by operational adjustments. Reducing the length of the combustion tunnels in the burners in a reheating furnace is suggested as another option for NOx reduction.
