A kinetic model of nitric oxide formation during pulverized coal combustion

Abstract

Abstract A mathematical model of nitric oxide (NO) formation during pulverized coal combustion was developed from a proposed kinetic mechanism involving 12 overall chemical reactions. Most significantly, the model describes the complex conversion of coal bound nitrogen compounds to NO during combustion. The predictions of the model compare favorably with literature data obtained in well defined laboratory combustors firing gaseous fuels doped with organic nitrogen additives, as well as with data obtained in laboratory coal combustors. The predictions of the model are in qualitative agreement with trends observed in practical coal combustors.
