Electrostatic precipitators are widely used at power-generating stations primarily due to their high efficiency in removing fly ash and other fine particulate matter from the combustion gases of fossil-fuel furnaces. These devices can capture particles as small as 1 micrometer with an efficiency exceeding 99 percent, which is critical for meeting clean-air regulations and protecting public health from the respiratory and environmental damage caused by particulate emissions.123

Beyond their high performance, these precipitators are favored because they can handle large volumes of gas at various temperatures and flow rates without significantly impeding the flow of exhaust gases. By applying a high-voltage electric charge to particles, the system forces them to collect on grounded plates, allowing for the effective cleaning of flue gases before they are released into the atmosphere. This capability makes them an essential tool for industrial facilities and power plants tasked with reducing harmful pollutants.213
