A system for the purification of the particulate present in fumes and in exhaust gases in combustion processes comprises an Ionizing Part (PI) and a Collection Pan (PR). The Ionizing Part (PI) comprises a perforated portion (40, 50) with at least one electron emitter in the holes (42, 52), consisting of one or more tips (P) to which a negative voltage is applied to create an electron cloud. The negative power supply is provided by a constant voltage generator. The fumes and exhaust gases arc passed through the Ionizing Part (PI) to transfer a negative charge to the particles of the particulate present in the flow of fumes and exhaust gases. The Collection Part (PR) comprises a plurality of positively loaded facing and spaced plates (22b) interposed with a plurality of shield plates (20b) to which no voltage is applied and are not connected to ground, to collect the particles of particulate previously negatively charged.
