Abstract (en)

[origin: ES8401601A1] Steam generator of the type comprising within a vertically axed type enclosure a plurality of U-tubes in which circulates a primary liquid and on the outer wall of which flows a secondary liquid, a cylindrical envelope surrounding the said tubes and defining with the inner wall of the enclosure an annular passage, whose lower part is connected to the inner space of the envelope, the latter being sealed in its upper part by a cover, which is itself surmounted by at least one device for separating the steam by centrifuging, a means for drying the steam in the upper part of the enclosure, said means incorporating at least one steam dryer surrounding the axis of the enclosure, each dryer being connected by its lower part to at least one discharge pipe for removing the water separated from the steam, wherein each discharge pipe is linked with a dynamic draining or bleeding device able to produce a pressure reduction or vacuum in order to suck in the water collected in the dryer. As a result, it is not necessary to maintain a clearance level or height in the discharge pipe. The steam generator is more particularly intended for use in pressurized water nuclear reactors.
