Question

Given below are two statements:

Statement I: Electrostatic precipitator is most widely used in thermal power plant.

Statement II: Electrostatic precipitator in thermal power plant removes ionising radiations.

In the light of the above statements, choose the most appropriate answer from the options given below:

Accepted Answer

B. 1. **Recall what an electrostatic precipitator (ESP) does**: An ESP is a device that removes **particulate matter (like dust and soot)** from the exhaust gases of thermal power plants, using electrically charged plates that attract and trap the charged dust particles.

2. **Evaluate Statement I**: Since ESPs are indeed the most common and effective device installed in thermal power plants to control particulate air pollution, Statement I is **correct**.

3. **Evaluate Statement II**: The purpose of an ESP is to remove suspended solid particles from smoke, **not** to remove ionising radiations (which are a completely different physical phenomenon related to radioactive decay or high-energy radiation, not solid pollutants). So Statement II is **incorrect**.

4. **Conclude**: Statement I is true while Statement II is false.

Hence, the answer is **B. Statement I is correct but Statement II is incorrect.**
