The ratio of maximum adiabatic flame temperature in air to that in pure oxygen is always___________________?
Correct answer: B. < 1
- A. 1
- B. < 1
- C. > 1
- D. Unpredictable
Explanation
Air contains mostly nitrogen, which absorbs heat without contributing oxygen, so the adiabatic flame temperature in air is lower than in pure oxygen. Therefore, the ratio of air-fired to oxygen-fired maximum flame temperature is less than 1.
