Flue gas outlet temperature from the chimney of any furnace should be ideally about ______________ °C?
Correct answer: C. 150
- A. 50
- B. 100
- C. 150
- D. 250
Explanation
A chimney outlet temperature of about 150°C is a practical compromise: lower temperatures risk condensation and poor draught, while much higher temperatures waste useful sensible heat. Therefore 150°C is the usual ideal value among these choices.
