Title (EN) HEATING SYSTEMS BASED ON ALTERNATING-CURRENT ELECTRODES
(FR) SYSTEMES DE CHAUFFAGE A ELECTRODES A COURANT ALTERNATIF
Abstract:
(EN) A self-protecting heating system and process of heating comprises an electrical circuit comprising an alternating current source (1), at least two electrodes (4, 5) made of passive metals, passive alloys, noble metals or alloys thereof, and electrically-conductive medium, wherein the two poles of said alternating electric current source (1) are in electrical contact with at least one electrode (4, 5) at each pole, and said electrodes (4, 5) are both in electrical contact with said electrically-conductive medium.
(FR) Un système de chauffage auto-protecteur et un procédé de chauffage comprennent un circuit électrique présentant une source de courant alternatif (1), au moins deux électrodes (45) en métaux passifs, en alliages passifs (1), en métaux nobles ou en alliages de ceux-ci, ainsi qu'un milieu électroconducteur, les deux pôles de ladite source (1) de courant électrique alternatif sont en contact électrique avec au moins une électrode (4, 5) à chaque pôle, et lesdites électrodes (4, 5) sont l'une et l'autre en contact électrique avec ledit milieu électroconducteur.
