Abstract

Dispositif destiné à équiper des échangeurs de chaleur pour éviter que le système de tubes chauffé par de la vapeur ne subisse une érosion en cas d'amenée de vapeur de chauffe contenant de l'eau et qui passe par des fenêtres d'entrée de vapeur dans l'espace à vapeur. Les fenêtres d'entrée de vapeur comportent individuellement un remplissage perméable au mélange vapeur/eau et dont la densité est telle que l'énergie cinétique de l'eau libre entraînée avec la vapeur se trouve dissipée en grande partie par le remplissage lors du passage du mélange vapeur/eau à travers celui-ci. L'invention est applicable par exemple dans des échangeurs de chaleur servant au réchauffage de l'eau d'alimentation de centrales nucléaires à vapeur.
