In thermal power stations, coal is burnt to produce steam for generation of electricity. The smoke produced is passed through electrostatic precipitators before allowing it to escape into the atmosphere. Answer the following question : Why is smoke passed through electrostatic precipitators in thermal power stations?

Read the following statements carefully. (i) An electrostatic precipitator removes particulate matter by imposing negative charge on them. (ii) Catalytic converters convert unburnt hydrocarbons into CO_(2) and water. (iii) Peroxyacyl nitrates (PAN) is a secondary pollutant. (iv) DDT is a non-biodegradable pollutant. Which of the above statements are incorrect ?

Assertion : An electrostatic precipitator (ESP) is a particulate collection device that removes dust and smoke particles from flowing air using the force of an induced electrostatic charge. Reason : An ESP is a highly efficient device as it removes 99 percent of particulate matter present in the exhaust from a thermal power plant.
