Question
A gas containing only CH4 and N2 is burned with air yielding a flue gas that has an Orsat analysis of 8.7% CO2, 1.0% CO,
A gas containing only CH4 and N2 is burned with air yielding a flue gas that has an Orsat analysis of 8.7% CO2, 1.0% CO, 3.8% O2 and 86.5% N2. Calculate the percent excess air used in the combustion and the composition of the CH4/N2 mixture. Why is CO produced during combustion? The following reactions apply:
CH4 + 3/2 O2 CO + 2H2O
CH4 + 2O2 CO2 + 2H2O
