Abstract

L'invention concerne un procédé permettant de faire démarrer un générateur de vapeur à fonctionnement continu (1) dont les tubes d'évaporation (4) sont parcourus de haut en bas côté eau d'alimentation. Afin d'éviter les pertes au démarrage, l'eau éjectée des tubes d'évaporation (4) côté sortie est renvoyée au moins en partie dans lesdits tubes d'évaporation (4) côté entrée. L'invention concerne également un système de démarrage comportant un conduit de décharge (44) qui relie la sortie (10) de l'évaporateur à l'entrée (8) dudit évaporateur.
