First we have to calculate the amount of POC. Combustion is complete with theoretical amount of air, POC consists of , and We can calculate the amount of each constituent of POC by the stoichiometry of the reaction as illustrated in the lectures on combustion (Lecture 9-11).
We can calculate heat carried by each constituent of POC at each temperature by using m × Cp × dT. The calculated values are given in the table
POC
Sensible heat (kcal) at T =1000K
Sensible heat (kcal) T=1100K
Sensible heat (kcal) T = 1200K
Sensible heat (kcal)T = 1400K

Increase in temperature from 1000K to 1400K decreases GAH by 19%. Decrease in GAH is followed by increase in fuel consumption in the same proportion
