Which of the following gaseous fuels has the highest net calorific value (kcal/Nm3) ?
Correct answer: D. Liquefied petroleum gas
- A. Producer gas
- B. Carburetted water gas
- C. Natural gas
- D. Liquefied petroleum gas
Explanation
LPG consists mainly of propane and butane, which release far more heat per normal cubic metre than the dilute combustible gases in producer gas or carburetted water gas. Natural gas is also energy-rich, but its methane content gives a lower value than LPG on this basis.
