In large thermal power stations very fine particulates present in flue gas are removed by___________________?
Correct answer: C. Electrostatic precipitators
- A. Wet scrubber
- B. Bag filter
- C. Electrostatic precipitators
- D. Dust catcher
Explanation
Electrostatic precipitators impart charge to fine particles and collect them on oppositely charged plates, making them effective for the large flue-gas flows of thermal power stations. Dust catchers mainly remove coarse particles, while bag filters are less suited to very large hot flue-gas streams.
