Abstract
Device for preventing thermal stratification for a steam generator feed pipe. A fixed helix (14) downstream of a rising break (12) of the pipe subdivides its interior into twisted channels. The cold water entering at a low flame rate is blocked upstream until a predetermined height (h) is reached and completely fills an upstream part (11) to be protected against thermal gradients.
