Most efficient and suitable dust removal equipment for removal of fly-ash from flue gas in a thermal power plant is the__________________?
Correct answer: B. Electrostatic precipitator
- A. Gravity settling chamber
- B. Electrostatic precipitator
- C. Cyclone separator
- D. Bag filter
Explanation
An electrostatic precipitator gives very high collection efficiency for fine fly ash in large thermal-power-plant flue-gas flows, with relatively low pressure drop. Gravity chambers and cyclones are less effective for fine ash, while bag filters can work but are generally less suitable for these very large, hot gas streams.
