In a coagulator for systems for the purifying of exhaust gases of fossil fuels, in particular of exhaust gases from diesel internal-combustion engines, which has a housing (10), poled as counter-electrode, an electrode (11) arranged concentrically in the housing (10) and at high volotage and an electrically heatable insulator (13) for the insulated leading of the electrode (11) through the housing (10), the insulator (13) is designed in two parts for achieving a great high voltage resistance with relatively small overall dimensions and consists of a ceramic inner tube (17) and a ceramic protective tube (18) surrounding the latter. The heating conductor track (19) required for heating is applied in the shape of a coil as a thick-film conductor to the circumference of the inner tube (17) and the protective tube (18) is sintered on to the inner tube (17) in such a way that the parting line (14) between inner and protective tube (17, 18) is gas-tight (FIG. 1).
Coagulator for systems for purifying the exhaust gases of fossil fuels from diesel internal-combustion engines, with a housing, poled as counter-electrode and cylindrical electrode, arranged concentrically in the housing and at high voltage, and with at least one insulator surround the electrode over a section of its length for the insulated leading of the electrode through the housing, which insulator bears an electric heating conductor track for the prevention or elimination of an agglomerate deposit on its surface, wherein the insulator (13;
