Abstract
A steam generator has a pressure vessel containing a stack of exchange tubes and a feedwater header of ring shape connected to a feed water intake pipe passing through the wall of the vessel. A horitzontal section of the pipe contains at least one deflector comprising an axial hub and several helical blades connecting the hub to the wall of the pipe. The blades have a length which represents at least half a winding pitch if the deflector is to counteract thermal stratification only, at least 1.5 winding pitch if for avoiding pressure surges.
