Abstract

In a preheating steam generator, the feed water is distributed in a feed space (34) by inverted J-shaped tubes (50), so as to mix with the recirculation water passing out of the water-steam separators, which ensures the preheating of said feed water. In order to prevent the latter rising again above the upper edge (30a) of skirt (30) externally defining the space (34), use is made of one or more of the four procedures consisting of partly obstructing by a plate (52) the top of space (34), downwardly extending tube (50), increasing the diameter in the vicinity of their end and upwardly extending skirt (30).
