Air/gas ratio for complete combustion will be the highest for__________________?
Correct answer: A. LPG
- A. LPG
- B. Gobar gas
- C. Coke oven gas
- D. Carburetted water gas
Explanation
LPG requires the most air per unit volume of fuel because it consists mainly of propane and butane, which need substantial oxygen for complete combustion. Methane-rich gobar gas and the hydrogen-rich manufactured gases require less air per unit gas volume.
