To change the temperature of a mass of 1 Kg of each by 2 degrees….
Air = 1006 J/kgC * 1kg* 2 C = 2012J
Fuel = 2100J/kgC*1kg*2 C = 4200J
Steel = 460J/kgC * 1kg * 2 C = 920J
Our 4200J of fuel energy goes to cool the 15C air…
4200J * 1kg /1006J/kgC = Change in T = 4.17 C
15C - 4.17C = 10.83C

I understand your (strong) point). Don't forget the stochio ratio (1 to 8 (?)) that even the above result.
Sry for the red thumb down... I hve really no idea how it came here
