The combustion characteristics of oxygen-enriched, laminar, premixed CO/H 2 /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/H 2 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% O 2 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 O 2 addition percentage. The possible drawback of such technology is predicted to be some increases in CO and NO emissions.
