How do vehicles reduce nitrogen oxides
Webburners, reburning, combustion staging, gas recirculation, reduced air preheat and firing rates, water or steam injection, and low excess air (LEA) firing. These modifications are capable of reducing NOx emissions by 50 to 80%. The method of combus- tion control used depends on the type of boiler and the method of firing fuel. Process Modifications Webfrom noncatalyst cars, which was lower than that found in the ambient air. Cars averaged 29 mg/mile when an oxidation catalyst was used, 61 mg/mile with a dual-bed catalyst, and 45 mg/mile with a three-way catalyst—the most commonly used catalyst today. Two vehicles were not included in the averages due to their very high emission levels—a ...
