Abstract

The present invention relates to a water supply pipe for a steam generator. The supply pipe comprises the following elements in a substantially horizontal portion (3) thereof: A lower baffle plate (4) defining or limiting an upper opening (7), And an upper baffle plate (5) defining or limiting a lower opening (9) and being disposed upstream of the lower baffle plate with respect to the normal flow direction of the water. The horizontal edge (8) defining the upper opening is disposed higher than the horizontal edge (10) defining the lower opening. As a result, the two baffle plates form between them a hydraulic barrier, which, when the water supply is cut off or reduced, prevents or substantially limits the passage of steam coming from the generator.

Claims3

Dependent claims

In combination, a steam generator, a water supply pipe coupled to said steam generator for supplying water thereto, the improvement wherein said water supply pipe comprises the following elements:

a horizontal or substantially horizontal pipe portion,
a lower baffle plate disposed in the pipe portion,
an upper opening defined by the lower baffle plate,
a horizontal lower edge defining the upper opening,
an upper baffle plate disposed in the pipe portion upstream of the lower baffle plate with respect to the normal flow direction of the water,
a lower opening defined by the upper baffle plate,
a horizontal upper edge which defines the lower opening and which is situated lower than the horizontal lower edge such that the two baffle plates together form a hydraulic barrier which, when the water supply is cut off or reduced, prevents or substantially limits the passage of the steam produced by the generator, this steam then condensing upstream of the upper baffle plate in contact with the water and restoring the hydraulic barrier.
