Abstract

Préchauffeur d'eau d'alimentation équipé d'un séparateur d'humité de vapeur. Pour séparer l'eau de la vapeur entrant dans un préchauffeur d'eau d'alimentation, on a prévu des rangées de profilés 7, 8, 9 formés de tubes ou d'autres corps prismatiques qui entourent les tubes 5 de l'échangeur de chaleur à distance étagée. On évite ainsi l'érosion des tubes 5 d'échange thermique. Les rangées de profilés sont fixées sur une plaque de retenue munie pour recueillir l'eau séparée, d'un rebord et d'un tube d'évacuation d'eau, ce dernier se terminant au-dessous du niveau d'eau du préchauffeur d'eau d'alimentation.
