Abstract

A steam generator of the type used as a component of a pressurized-water power reactor installation, has a preheater to which feed water is supplied via a plenum chamber of extended length connecting with the preheater through a series of holes. The plenum chamber is supplied with feed water via the generator's feed-water inlet nozzle which injects a feed-water jet which impinges on an inner wall of the plenum chamber for deflection thereby and flow throughout the plenum chamber. This jet is surrounded by a perforated cylinder through which the deflected feed-water flow must pass for distribution throughout the plenum chamber, the effect being a more uniform distribution of the feed-water flow throughout the plenum chamber and a reduction in the flow resistance which otherwise prevails.
