What is a flame temperature?
It is the temperature attained by the products of combustion, when fuel is burnt with air or oxygen. Flame temperature is difficult to measure when combustion of a mixture of fuel + air occurs inside the furnace.
But flame temperature may be calculated
Method of calculation
Heat balance is done to calculate the flame temperature
| [Sensible heat in air + fuel] + [Heat of combustion]-[Heat absorbed due to dissociation of products of combustion] = (Sensible heat in POC) + [Heat losses from flame to surrounding] |
