Which of the following accounts for maximum energy loss in a boiler ?
Correct answer: A. Flue gases
- A. Flue gases
- B. Ash content in the fuel
- C. Incomplete combustion
- D. Unburnt carbon in flue gases
Explanation
Flue-gas loss is usually the largest boiler loss because a large mass of hot exhaust gases carries sensible heat out of the furnace. Ash, incomplete combustion and unburnt carbon can cause losses, but are generally smaller in a properly operated boiler.
