Abstract

Un élément de base (1) d'une installation de l'industrie primaire émet dans une première phase (P1) du cycle d'installation des gaz brûlés chauds, et peu ou pas de gaz brûlés dans une deuxième phase (P2) du cycle d'installation. Les gaz brûlés sont évacués par un système de conduites tubulaires (2). Un évaporateur (5, 7) intégré à cet endroit permet d'évaporer de l'eau au moins dans la première phase (P1) et d'amener les vapeurs vers un dispositif de stockage de vapeur (9, 11). Dans la première phase (P1), la vapeur stockée est guidée sur un surchauffeur intégré au système de conduites tubulaires (2) et surchauffée au niveau de celui-ci. Une première partie de la vapeur surchauffée est guidée dans un sens de chargement à travers un réservoir tampon (16). La vapeur chauffe un milieu de stockage situé dans le réservoir. La vapeur surchauffée résiduelle est guidée vers une turbine à vapeur (17) tout en contournant le réservoir tampon (16). Dans la deuxième phase (P2), de la vapeur saturée est prélevée dans le dispositif de stockage de vapeur (9, 11), guidée au moins partiellement à travers le surchauffeur (6) et combinée à de la vapeur surchauffée prélevée dans le réservoir tampon (16) contre le sens de chargement. La combinaison des deux courants de vapeur est guidée vers la turbine à vapeur (17).
