<p>In a hot-water boiler equipped with means (3, 20) for electrochemical protection, a tank (1) made of corrodible metal and a flanged metal cap (5) which requires electrochemical protection but prevents an adequate supply of protection current to the other metal components (1) to be protected owing to the vicinity of a feed electrode, said metal cap (5) is fastened to the tank (1) so that it is connected electrically to it only by way of a resistor (11). In the near vicinity of said metal component (5) and electrically isolated from it, a grounding device (9) is envisaged which intercepts any flashovers generated by failures.</p> |
