The maximum adiabatic flame temperature is attained, when the fuel is burnt with ______________________?
Correct answer: B. Theoretically required amount of oxygen
- A. Theoretically required amount of air
- B. Theoretically required amount of oxygen
- C. Less than theoretically required amount of air
- D. More than theoretically required amount of air
Explanation
A stoichiometric quantity of pure oxygen gives the highest adiabatic flame temperature because no nitrogen is present to absorb heat and dilute the flame. Stoichiometric air gives a lower temperature due to its large nitrogen content.
