Steam generator with preheater
Description
In steam generator with preheater, the feedwater is distributed into a feed space by inverted tubes in J form so as to preheat by mixing it by the recirculation water coming from the steam-water separators. To prevent the feedwater remaining above the top edge of the skirt defining the external limit of the feed space one or more of four techniques are used: (1) partial obstruction at the top of the feed space by a plate (2) lenghtening of the lower end of the tubes (3) increasing the lower end diameter of the tubes (4) increasing the height of the skirt

Dans un generateur de vapeur a prechauffage, l'eau alimentaire est distribuee dans un espace d'alimentation par des tubes en forme de J renverses, de facon a se melanger avec de l'eau de recirculation sortant des separateurs eau-vapeur, qui assure le prechauffage de cette eau alimentaire. Afin d'eviter la remontee de cette derniere au-dessus du bord superieur de la jupe delimitant exterieurement l'espace, on utilise une ou plusieurs des quatre techniques consistant a obstruer partiellement par une plaque le haut de l'espace, prolonger vers le bas les tubes, en augmenter le diametre a proximite de leur extremite, et prolonger la jupe vers le hautAdditional details
