ABSTRACT:
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.
