Module 2: Combustion and heat utilization
  Lecture 13: Flame Temperature
 

 

Rearrangement.

Tf = 2034 K

Similarly for 50% excess
POC:     

CO2 = 0.968
H2O = 1.92
O2 = 1.0
N2 = 11.31

Heat balance yields

We note that increase in excess air decreases flame temperature. This is due to increase in N2 and O2 in the POC.
Similar calculations can be done by enriching air with O2.
