Thanks,
Here is my calculation:
C15H32+29.899 O2+112.42 N2=13.649 Co2 + 1.350 CO +7.574 O2+112.425 N2+ 15.998 H2O
And for the theoretical air:
C15H32+ 23 O2+ 86.48 N2=15 CO2+ 16 H2O+86.48 N2
AFR(theoretical) = (28.8*(23+86.48))/212 = 14.872
AFR(stoich) = (28.8*(29.899+112.42))/212 = 19.333
Excess air = 19.333/14.872 = 1.3 or 30%

Looks good?
