An electrostatic precipitator serves the critical function of eliminating particulate emissions in a power plant. It is a sophisticated air pollution control device designed to capture fine particles from the exhaust gases emitted during the combustion of fossil fuels. These devices work by charging the particles as they pass through the precipitator; the charged particles are then attracted to oppositely charged plates, where they accumulate and are subsequently collected.

This process significantly reduces the amount of particulate matter—such as soot, dust, and metal oxides—released into the atmosphere, thereby helping power plants meet environmental regulations and improve air quality. The effectiveness of electrostatic precipitators in capturing particulates makes them an essential component in modern power plant operation, contributing to cleaner emissions and a reduced environmental impact.
