Thus TMAFT or AFT is > Actual flame temperature.

For adiabatic combustion and without dissociation of POC and from assumptions 2 and 4 one can write eq. 1 as

for fuel and air for all combustion reaction = combustion products.

(3)

T is temperature at which reactants are heated. If T = 298K ten sensible heat of reactants is zero.

(4)

Where T_f is the flame temperature and

(5)

n₁ = moles of specie of specific heat C_P

i= No. of specie in a mixture, for example in air we have O₂ and N₂ and in POC we have CO₂, H₂O and N₂ etc.
