A chemical kinetics study of oxygen-enriched CO/H2/air flames
The combustion characteristics of oxygen-enriched, laminar, premixed CO/H2/air flames at atmospheric conditions have been investigated using the CHEMKIN III chemical kinetic simulation package along with the GRI 3.0 kinetic mechanism. The CO/H2 ratio has been kept at 19, while varying the fuel/air equivalence ratio from 0.4 to 1.2. The effects of 5%, 10%, and 20% oxygen enrichment (in addition to the 21% O2 in air) are expressed in terms of burning velocities, flame temperatures, and pollutant concentrations. Increases in burning velocity and in adiabatic flame temperature are calculated relative to the O2 addition percentage. The possible drawback of such technology is predicted to be some increases in CO and NO emissions.
