Short/intense flame is produced during combustion of gaseous fuel by using________________?
Correct answer: A. High amount/current of combustion air
- A. High amount/current of combustion air
- B. Low amount/current of combustion air
- C. Preheated secondary air
- D. Very little excess air
Explanation
A high rate or velocity of combustion air promotes rapid turbulent mixing with the gas, producing a short, intense flame. Low air supply generally gives slower mixing and a longer, less intense flame.
