Claims (6)

1. Générateur de vapeur comportant un premier carneau vertical (10) fabriqué à partir de tubes (17) soudés étroitement et comportant une chambre de combustion, un second carneau vertical (11) voisin et un carneau transversal court (15) reliant le deuxième carneau vertical au premier et raccordé dans la zone supérieure des carneaux verticaux (10, 11), ainsi qu'une charpente de cuve (2, 4, 5) pour porter le générateur de vapeur, de telle manière que, pour recevoir le poids des parois tubulaires (12, 13; 12', 14) du premier et du second carneau vertical (10 ou 11) dans la zone haute près du dessous du carneau transversal (15), on dispose respectivement un système porteur (7, 8) qui est relié près du dessous du carneau transversal à la charpente de cuve (2, 4, 5) et, au voisinage de chacun des systèmes porteurs (7, 8), une membrure (64 ou 65) entourant le carneau vertical correspondant (10, 11) et supportée dans les directions horizontales principales sur la charpente de cuve (2, 4, 5), générateur caractérisé en ce que chacun des systèmes porteurs (7, 8) comprend une pluralité de leviers (30) à deux bras dont chacun est supporté au moyen d'un appui oscillant (35) et d'un élément de traction (37) sur un châssis (5) s'étendant horizontalement de la charpente de cuve (2, 4, 5) et est relié à une extrémité à l'une des parois tubulaires (12, 13; 12', 14) du carneau correspondant.
2. Générateur de vapeur selon la revendication 1, caractérisé par le fait que chaque appui oscillant (35) et/ou chaque tirant (37) est réalisé élastique dans le sens longitudinal.
3. Générateur de vapeur selon la revendication 1 ou 2, caractérisé par le fait que la longueur des appuis oscillants (35) et/ou des tirants (37) est ajustable.
4. Générateur de vapeur selon les revendications 2 et 3, caractérisé par le fait que des vérins hydrauliques (60, 61) sont prévus pour bander les ressorts lors de l'ajustement de la longueur des appuis oscillantrs (35) ou des tirants (37).
5. Générateur de vapeur selon l'une des revendications 1 à 4, caractérisé par le fait que plusieurs languettes de tôle (21) et un gousset oscillant (24) sont prévus entre les parois tubulaires (12, 13, 12', 14) et chacun des leviers (30) à deux bras.
6. Générateur de vapeur selon l'une des revendications 1 à 5, caractérisé par le fait que les tubes du second carneau vertical (11) et du carneau transversal (15) sont soudés hermétiquement.
