A fuel oil burned in a steam generator has a composition that may be represented as C15H32.
A dry basis analysis of the flue gas yields the following molar composition: CO2 10.111%,
CO 1.000%, O2
5.611%, and N2 83.278%.
Determine the following:
(a). The percent excess air used to burn the fuel oil;
(b). The flue gas molar composition on a wet basis, reporting all constituents, including
water vapor, to the nearest 0.001%; and
(c). The dew point temperature (°C) of the flue gas, if the pressure exiting the combustion
I am trying to balance the combustion equation:
aC5H32 + bO2 + cN2 = 10.111CO2 + 1.000CO + 5.611O2 + 83.278N2 + dH2O
Any idea of how to do it considering #N2=#O2*3.76 ?
Thanks
stack is 180 kPa

Separate your equation into independent reactions and balance each. After that you can mix these reactions in any required proportions.
C5H32 + O2 = CO2 + H2O
C5H32 + O2 = CO + H2O
Add nitrogen in required proportion: it is not participating in burning process, so it should be equal and unchanged in the reagents and in the products.
C5H32 + O2 = CO2 + H2O

Remember safety first! Check MSDS and consult with professionals before performing risky experiments.
