Claims (5)

  1. Condenseur à vapeur à disposition au niveau du sol ayant une turbine à vapeur, la vapeur se condensant dans des tuyaux (5) parcourus d'eau de refroidissement et groupés en faisceaux partiels séparés (2) et les tuyaux disposés en rangées d'un faisceau enveloppant une cavité (13), dans laquelle est disposé un refroidisseur (14) pour les gaz non condensables, refroidisseur (14) au travers duquel est aspiré le mélange de gaz non condensables et de vapeur d'eau, qui s'accumule dans la cavité (13) du faisceau partiel (2), caractérisé en ce que
    - les faisceaux partiels (2) sont dirigés horizontalement dans leur extension longitudinale,
    - plusieurs faisceaux partiels sont disposés les uns au-dessus des autres dans la direction verticale,
    - et le refroidisseur (14) présente au sein d'un faisceau partiel une forme asymétrique, qui est choisie en fonction de la charge asymétrique de condensat dans le faisceau partiel dirigé horizontalement et de la localisation asymétrique du minimum de pression dans l'assemblage de tuyaux,
    - et la section transversale d'aspiration du refroidisseur (14) a son centre de gravité sous la ligne médiane longitudinale (22) du faisceau partiel, à l'endroit de la pression minimale, qui est le lieu d'accumulation des gaz non condensables.
  2. Condenseur à vapeur selon la revendication 1, caractérisé en ce que les tuyaux de refroidisseur (14) sont pourvus dans la cavité (13) du faisceau (2) d'une tôle de recouvrement (19), qui est conçue sous forme de canal d'aspiration fermé (17), ce dernier communiquant avec la zone la plus froide du refroidisseur par l'intermédiaire d'écrans (18).
  3. Condenseur à vapeur selon la revendication 2, caractérisé en ce que le mélange air/vapeur affluant du refroidisseur dans le canal d'aspiration est aspiré hors du canal par l'intermédiaire d'au moins une conduite d'aspiration (20) traversant le faisceau, ceci étant réalisé en ce qu'il manque une ou deux rangées de tuyaux au sein du faisceau partiel dans l'enveloppe par ailleurs fermée et on les a remplacées par des tuyaux inactifs (21).
  4. Condenseur à vapeur selon la revendication 1, caractérisé en ce qu'à chaque fois entre deux faisceaux partiels (2) est disposée une tôle de collection de condensat (11), qui est dirigée horizontalement et s'étend au moins du niveau du refroidisseur (14) jusqu'au voisinage de la base (8) du condenseur.
  5. Condenseur à vapeur selon la revendication 1, caractérisé en ce que l'unité de construction coquille de condenseur/faisceau partiel/tôles de collection de condensat est légèrement inclinée par rapport à l'arbre (24) de la turbine dans la direction longitudinale des tuyaux.
