Q. What happens due to high temperature of feeds water in the economizer?

  • (A) fuel consumption increases
  • (B) fuel mechanical efficiency increases
  • (C) fuel consumption decreases
  • (D) fuel mechanical efficiency decreases

✅ Correct Answer: (C) fuel consumption decreases
Explanation: function of the economizer is to recover a portion of heat of the exhaust gases before the flue gases enter the chimney and discharged to the atmosphere. due to the high temperature of feed water, fuel consumption reduces. this increases the overall efficiency of the boiler.
