Higher fuel combustion efficiency cannot be achieved by_________________?
Correct answer: B. Reducing sulphur content in the fuel
- A. Preheating of fuel gases & combustion air
- B. Reducing sulphur content in the fuel
- C. Adopting proper fuel firing technique & fuel preparation
- D. Supplying correct amount of combustion air
Explanation
Sulphur reduction mainly lowers SOx emissions, corrosion, and pollution; it does not directly improve the completeness or efficiency of combustion. Preheating, proper firing, and correct air supply promote more efficient burning.
