Calculation of Enthalpies and

Adiabatic Flame Temperature

Ex A fuel gas containing $22\%CO,13\%C{O}_2$ and $65\%N_2$ by volume is combusted with

the theoretically required amount of air in a furnace to heat a solid burden. The gases

enter the furnace at $250C$ Calculate the adiabatic flame temperature.

Can anyone help me solving this with exel and factsage module?

I know the process without using excel and factsage module. I want to know how to solve with using excel. Also I need accurate anwer. Professor said that he will write this question at his exam. Please help me$..!$
