Abstract

Pour réaliser une installation rapide et sûre d'extinction d'incendie dans un système de stockage (10), il est prévu une installation d'extinction se fondant sur le principe de l'inertage, dans lequel ou bien on assure un noyage homogène de la totalité du système de stockage (10), ou bien on assure un noyage ciblé de zones à risque. A cette fin, on a prévu des gaines de gaz extincteur (62), en particulier verticales, comportant un grand nombre d'ouvertures (66) pour la sortie du gaz extincteur, chaque groupe d'ouvertures (56) de sortie du gaz d'extinction étant affecté à une zone de noyage (F1 à F3), ou encore une conduite de répartition de gaz d'extinction, comportant plusieurs buses de pulvérisation.
