The present invention relates to an electrostatic precipitator (ESP) system (1) for removal of particles from a flue gas flowing in a flow passage (4) being delimited by a primary collection in the form of a collection plate (5). The system comprises a discharge electrode (11) arranged in the flow passage and connected to a high voltage generator (12) providing for an electric field around the discharge electrode. The system further has a secondary collection electrode in the form of a grid (101) arranged within the collection plate and made of an electrically conductive material. The presence of such a grid improves the efficiency of the precipitator. In some embodiments, the ESP system comprises an actuator (112) for moving the grid upwards and letting it drop onto an internal bottom structure (109). The movement between the collection plate and the grid as well as the impact force imparted to the dropping grid both result in a removal of collected particles.
