Nitric Oxide Formation In Combustion
Abstract
A review of the current understanding of nitric oxide production in hydrocarbon/air and hydrogen/air combustion processes shows that the extended Zeldovich mechanism yields accurate nitric oxide predictions for fuel/air equivalence ratios from zero to infinity for hydrogen combustion and from zero to about 1.5 for hydrocarbon combustion. The theory cannot predict the fuel-rich hydrocarbon results because important, yet to be discovered reactions or reaction mechanisms are missing. The oxygen atom concentration exerts considerable influence on the nitric oxide production rate. It should be calculated by using a partial equilibrium assumption of the H2-O2-CO reactions: H+O2⥤OH+O, O+H2⥤OH+H, H2+OH⥤H2O+H, and CO+OH⥤CO2 +H. The nitric oxide emission predictions, when compared to experimental measurements, verify the theoretical analysis. © 1976 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
