Which is the most efficient dust removal equipment for removal of submicronic dust particles from blast furnace gas ?
Correct answer: A. Electrostatic precipitator
- A. Electrostatic precipitator
- B. Gravity settling chamber
- C. Packed scrubber
- D. Hydrocyclone
Explanation
An electrostatic precipitator can remove very fine, submicronic particles by electrically charging them and collecting them on oppositely charged plates. Gravity chambers and hydrocyclones are ineffective for such small particles.
