Title (EN) STEAM GENERATOR AND METHOD OF SECURING TUBES WITHIN A STEAM GENERATOR AGAINST VIBRATION
(FR) GÉNÉRATEUR DE VAPEUR ET PROCÉDÉ DE PROTECTION DE TUBES CONTRE DES VIBRATIONS À L'INTÉRIEUR D'UN GÉNÉRATEUR DE VAPEUR
Abstract:
(EN) A steam generator (2) includes a tube bundle (200,300,500) having a plurality of tubes, arranged in rows and columns. The first column of tubes (210,310,510) includes a first tube (212,312) having a curved center line (214) disposed in a first plane (216,316,516). The second column of tubes (230,330,530) includes a second tube (232,332) having a curved center line (234) disposed in a second plane (236,336,536), the second plane being parallel to and spaced a distance (206,306) from the first plane. The steam generator further includes a first number of solid anti-vibration bars (220,320,520) disposed between the first column of tubes and the second column of tubes; wherein each of the tubes has a tube outer diameter (204,304); and wherein each of the first number of anti-vibration bars has a thickness (222,322,522) generally transverse to the first and second planes, the thickness being greater than the distance between the first and second planes minus the tube outer diameter.
(FR) La présente invention concerne un générateur de vapeur (2) comprenant un faisceau de tubes (200, 300, 500) comportant plusieurs tubes disposés en rangées et en colonnes. La première colonne de tubes (210, 310, 510) comprend un premier tube (212, 312) présentant un axe courbe (214) disposé dans un premier plan (216, 316, 516). La seconde colonne de tubes (230, 330, 530) comprend un second tube (232, 332) présentant un axe courbe (234) disposée dans un second plan (236, 336, 536), le second plan étant parallèle au premier plan et étant espacé de ce dernier d'une certaine distance (206, 306). Le générateur de vapeur comprend en outre un premier nombre de barres anti-vibrations (220, 320, 520) pleines disposées entre la première colonne de tubes et la seconde colonne de tubes ; chacun des tubes ayant un diamètre extérieur (204, 304) de tube ; et chaque barre du premier nombre de barres anti-vibrations ayant une épaisseur (222, 322, 522) globalement transversale par rapport au premier et au second plans, l'épaisseur étant supérieure à la distance qui sépare les premier et second plans moins le diamètre extérieur de tube.
