The dust collection efficiency of electrostatic precipitator increases with increase in the_________________?
Correct answer: B. Electrode area
- A. Gas flow rate
- B. Electrode area
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
For an electrostatic precipitator, collection efficiency increases with collecting electrode area because more surface is available for charged particles to deposit. Increasing gas flow rate generally reduces efficiency by shortening residence time, so option A is not correct.
