Abstract

Basically, 95% or more of nitrogen oxides (NO*) emitted from a coal fired power plant are in the form of nitric oxide (NO). The dispersion of the plume from this point source produces the entrainment and mixing with background ozone (Osbg). This process is completed with the oxidation of NO to NCfe and the photodisociation of NOz to NO and Oa. NO: is considered a health hazard. The net transformation of NO to NO% is driven by the atmospheric turbulence (mixing), by chemical reactions and by ultraviolet radiation. To simulate the effect of an NO* emitting plume to the pollutant's ground level concentration,
