Abstract

L'invention concerne un procédé pour le maintien ou l'extension de la plage de température d'exploitation à long terme, d'un milieu caloporteur et/ou d'un milieu accumulateur de chaleur, renfermant une composition de sel de nitrate, choisie dans le groupe constitué par un nitrate de métal alcalin et un nitrate de métal alcalinoterreux et, éventuellement, par un nitrite de métal alcalin et un nitrite de métal alcalinoterreux, caractérisé en ce que la composition de sel de nitrate est mise en contact avec un additif renfermant les composants acide nitrique et/ou acide nitreux, et un gaz oxygéné ayant une pression partielle d'oxygène qui est égale ou supérieure à celle dans l'air, et/ou des composés générant de l'oxygène, et, éventuellement, des oxydes d'azote et/ou d'autres composés générant de l'oxyde d'azote.The invention relates to a method for maintaining or extending the long-term operating temperature range, a heat-transfer medium and / or a heat-storage medium containing a selected nitrate salt composition. in the group consisting of an alkali metal nitrate and an alkaline earth metal nitrate and, optionally, an alkali metal nitrite and an alkaline earth metal nitrite, characterized in that the nitrate salt composition is contacted with an additive containing the nitric acid and / or nitrous acid components, and an oxygenated gas having an oxygen partial pressure that is equal to or greater than that in the air, and / or oxygen generating compounds, and, optionally, nitrogen oxides and / or other compounds generating nitrogen oxide.
