Dust collection efficiency of electrostatic precipitator can be as high as 99.9%. Maximum temperature and pressure of dust laden gas that can be cleaned in an electrostatic precipitator is respectively ?
Correct answer: A. 1000°C and 10 atm
- A. 1000°C and 10 atm
- B. 200°C and 5 atm
- C. 500°C and 50 atm
- D. 1000°C and 500 atm
Explanation
Electrostatic precipitators can treat dust-laden gases at temperatures approaching 1000°C and pressures around 10 atm in the stated textbook range. Their high collection efficiency results from electrically charging particles and driving them to oppositely charged collecting plates.
