Electrostatic Precipitator


An electrostatic precipitator (ESP) is a piece of equipment that is used to capture dust particles that are formed or liberated by various industrial processes. The purpose of an ESP is to avoid these particulates being expelled into the atmosphere where they can cause pollution. ESPs are installed at many types of industrial plant, but they are most easily identified at thermal power plants where they are installed as part of the flue gas cleaning system.

The diagram below shows the position of an ESP within a coal fired power station flue gas system. Another important component used for flue gas cleaning is the flue gas desulphuriser (FDG), also referred to as a ‘scrubber tower’; the scrubber tower is shown to the left of the ESP on the below diagram.
