Abstract
A self-protecting heating system comprises an electrically conductive medium, an alternating current source and at least two electrodes. The alternating current source is in contact with at least one electrode at each pole, and the electrodes are in electrical contact with the electrically conductive medium. The electrodes are made of passive metals or passive alloys. The electrically conductive medium may be an aqueous solution or water. The system is preferably provided with a thermostat that disconnects the electrical power from the electrodes once a desired temperature has been reached.
Claims16
A self-protecting heating system, which comprises an alternating current source having two poles, at least two electrodes made of material chosen from the group consisting of passive metals, which are metals covered with an oxide of the metal, and passive alloys, which are alloys covered with a layer of one of the metal elements which constitute the alloy, and an electrically-conductive medium, wherein the two poles of said alternating electrical current source are in electrical contact with at least one of the electrodes at each of the poles and said electrodes are both in electrical contact with said electrically-conductive medium.
Process of heating which comprises causing electrical contact between at least one electrode made of material chosen from the group consisting of passive metals, which are metals covered with an oxide of the metal, and passive alloys, which are alloys covered with a layer of one of the metal elements which constitute the alloy, to each pole of an alternating electrical current source, and further causing electrical contact between said at least ones electrodes and an electrically-conductive medium.
