Abstract (en)
The invention relates to an electrostatic precipitator unit (1) for insertion in a flue gas passageway. It comprises a pipe (4) in which a discharge electrode (5) is arranged, a high voltage generator (6) for providing an electric field being generated in a region around the discharge electrode, and a controller (8). A casing (9) extending from the pipe comprises a first compartment (101) adjacent to the pipe, and a second compartment (102) at a distance from the pipe and separated from the first compartment by a heat shield plate (103). The controller and the high voltage generator are arranged in the second compartment or in a third compartment (108). The walls of the casing are provided with ventilation holes (110,111) arranged to cause a flow of air along the second compartment as a result of thermal convection caused by hot flue gas flowing in the flow passage during use of the electrostatic precipitator unit.
