    摘要: The secondary water supply for a steam generator is provided by a toroidal or semitoroidal collector (38) placed in the bottom of the annular recirculation space (32) of the generator, in a larger diameter part (36) of the outer envelope. The collector (38) has holes (40) ensuring a vertical mean flow of the secondary water into the annular space (32). The cross-section of the holes is chosen in such a way as to trap in the collector the migrating bodies or members from the secondary water circuit and which could damage the steam generator tubes. At least one access orifice makes it possible to extract these migrating bodies from the collector during maintenance operations.

    摘要: The present invention concerns a process for the preparation of a 2-hydroxybenzoic acid and of a 4-hydroxybenzaldehyde and derivatives thereof from a mixture of two phenolic compounds, one carrying a formyl or hydroxymethyl group in the 2 position, and the other carrying a formyl or hydroxymethyl group in the 4 position. The invention also concerns the preparation of a 4-hydroxybenzaldehyde from said mixture. The invention more particularly concerns the preparation of 3-methoxy-4-hydroxybenzaldehyde and of 3-ethoxy4-hydroxybenzaldehyde, respectively known as “vanillin” and ethylvanillin”. The process for the preparation of a 2-hydroxybenzoic acid and a 4-hydroxybenzaldehyde and derivatives thereof is characterised in that the formyl or hydroxymethyl group in the 2 position of compound (A) in a mixture of phenolic compounds, one (A) carrying a formyl or hydroxymethyl group in the 2 position, and the other (B) carrying a formyl or hydroxymethyl group in the 4 position, is selectively oxidised to a carboxy group and optionally a hydroxymethyl group of compound (B) in the 4 position is selectively oxidised to a formyl group, thus producing a mixture of a 2-hydroxybenzoic acid and a 4-hydroxybenzaldehyde.
