The following combustion reactions occur when methane is burnt.
CH4+2O2→CO2+2H2O
2CH4+3O2→2CO+4H2O
20% excess air is supplied to the combustor. The conversion of methane is 80% and the molar ratio of CO to CO2 in the flue gas is 1:3. Assume air to have 80 mol % N2 and rest O2. The O2 consumed as a PERCENTAGE of O2 entering the combustor is
