For forced draught system, the function of chimney is mainly_____________?
Correct answer: B. to discharge gases high up in the atmosphere to avoid hazard
- A. to produce draught to accelerate the combustion of fuel
- B. to discharge gases high up in the atmosphere to avoid hazard
- C. to reduce the temperature of the hot gases discharged
- D. none of the above
Explanation
With forced draught, the fan supplies the combustion air, so the chimney is not primarily needed to create draught. Its main role is to discharge flue gases at a height that reduces danger and nuisance near the plant.
