QUESTION $8$

A fuel gas containing $22\mathrm{.}4\%CO,12\mathrm{.}6\%C{O}_2,$ and $65\%N_2$ by volume is burned with the

theoretically required amount of air in a furnace designed to heat solids. The gases enter the furnace

at $250C$ and leave it at $700C$ and $1$atm. Calculate:

a$.$ The adiabatic flame temperature, and

b$.$ The quantity of heat supplied to the solids in the furnace, in joules per cubic meter of

exhaust gases.
