Determine the NOx and CO emission index in g/kg-fuel for cases I & II. 2.Discuss the concentration trend of CO and NOx with various equivalence ratios in case I. 3.Discuss the concentration trend of CO and NQx with various equivalence ratios in case II, and interpret the fact of hydrogen addition in methane/air premixed flames in pollutant mitigation or enhancement. 4.Exemplify two fashions to mitigate CO and NOx concentration in hydrocarbon combustion
