The Electrostatic Precipitator is one of the most advanced technologies for particulate emission control, characterized by high efficiency and low operating costs.

Its collection method uses a high-voltage electrostatic field to separate particulates from the combustion gases.

The equipment consists of vertical parallel plates forming the gas passage, with negatively charged discharge electrodes positioned between them, and a high-voltage system that supplies electricity to these electrodes, generating an electric field.

Particulate material is carried by the gas stream and negatively charged as it passes through this field, being attracted to the grounded plates and forming a layer of ash on their surface.

Periodic rapping dislodges the accumulated material from the collecting plates and discharge electrodes, and the ash is collected in hoppers and/or chutes and directed to the ash handling system.

Electrostatic Precipitators can be designed to meet strict emission limits with minimal pressure drop and high equipment reliability, offering various advantages such as collection efficiency exceeding 99.5%, low operating cost since no water is required, reduced maintenance, and extended operational availability.

HPB leverages B&W’s technology and experience, with over 150 years in operation with steam generation systems and environmental control equipment.

B&W has implemented Electrostatic Precipitators in over 800 industrial plants worldwide, in a variety of sectors, providing safety and flexibility to each project.
