Electrostatic precipitators (ESPs) are widely used in industries to remove fines particles contained in flue gases and to prevent health diseases. This study was inspired by the need to replace, because of industrial constraints, an active emissive electrode called "Heritrode" previously developed, by a new emissive electrode (NE). In order to design this one, electric field modelling and experimental results are conducted. We will investigate the ESPs efficiency of the new electrode by studying the collection efficiency, the impact of different dust and by conducting voltage tests, in order to have the better managed in an economic and efficient way. Experimental tests are carried out on a single stage pilot located in the SIAME laboratory to perform the filtration efficiency of the new electrode.
