Control of NO x During Stationary Combustion

Nitrogen oxides (NO x ) and sulfur oxides (SO x ) emissions are primary contributors to acid rain, which is associated with a number of effects including acidification of lakes and streams, accelerated corrosion of buildings, and visibility impairment. Among the various nitrogen oxides emitted from stationary combustion; nitrogen oxide (NO), nitrous oxide (N2O), and nitrogen dioxide (NO2) are stable, and NO predominates (over 90%). In health effects, NO2 can irritate the lungs and lower resistance to respiratory infection. In the area of ozone nonattainment, NO x and volatile organic compounds (VOCs) react in the atmosphere to form ozone, a photochemical oxidant and a major component of smog. Atmospheric ozone can cause respiratory problems by damaging lung tissue and reducing lung function 1.
