Abstract
Nitrogen oxides (NO + NO2) belong to the most important gaseous pollutants from combustion processes. This review is concentrated on the mechanism and reaction kinetics of fuel nitrogen conversion to NO in combustion of solid fuels (coal, peat, wood). The mechanism and the kinetics of heterogeneous catalyzed and gas-solid non- catalyzed reactions of NO formation in solid fuel devolatilization and char combustion have been studied in terms of NO-precursor release (NH3 + HCN), precursor oxidation and decomposition. Destruction reactions (interactions and reduction reactions) of NO, mainly by char, CO and H2, are very important for final emissions of NO in combustion. Application of heterogeneous mechanisms and kinetics of fuel-N→NO formation and NO destruction is mainly in fluidized bed combustion, partly in pulverized coal combustion (where thermal NO formation may be significant).
