Correct Answer
Electrostatic precipitator
Detailed Explanation
Electrostatic precipitator can remove over 99% particulate matter present in the exhaust from a thermal power plant. It has electrode wires that are maintained at several thousand volts, which produce a corona that releases electrons. These electrons attach to dust particles giving them a net negative charge. The collecting plates are grounded and attract the charged dust particles.
