摘要： The secondary water supply for a steam generator is provided by a toroidal or semitoroidal collector (38) placed in the bottom of the annular recirculation space (32) of the generator, in a larger diameter part (36) of the outer envelope. The collector (38) has holes (40) ensuring a vertical mean flow of the secondary water into the annular space (32). The cross-section of the holes is chosen in such a way as to trap in the collector the migrating bodies or members from the secondary water circuit and which could damage the steam generator tubes. At least one access orifice makes it possible to extract these migrating bodies from the collector during maintenance operations.

摘要： In a preheating steam generator, the secondary water is introduced into a preheating space (34) by deformable extensions (52) from inverted J tubes (50) fixed to a semi-torroidal supply collector (48). The structure may be in the form of three tubular segments interconnected by swivel connections or couplings. The fitting of the extensions (52) between the tubes (50) and a plate (54) partly upwardly sealing the preheating space (34) is ensured by dismantable fixing members, without any welding.
