(For ease take air as 80% N2 20%O2 (ratio 4:1) C4H10+ a(O2+ 4 N2) => x CO2 +y H2O + z N2 a) For an excess air ratio of 2:1 show the new chemical equation b) For the excess air ratio of 2:1 calculate the adiabatic flame temperature (AFT) taking the details of gas properties from table A2 and lower calorific value of the fuel LCV from table A27. c) Calculate the AFT if an equal volume of cooled recirculated exhaust gas (and in this case assume this is all CO2) were also introduced with the excess air.
