Abstract

Device for condensing steam under pressure consisting of a unit incorporating a storage vessel (6) containing cooling water, a distribution and heat exchange unit (15) fixed inside the storage vessel (6) and a water supply (30,31) for replacing the water in a storage tank (6) which is vaporized by contact with the tubes (24) of the distribution and heat exchange unit (15). A stack (7) is connected to the upper part of the storage vessel (6) and a tranquilizer grid is arranged in the storage vessel, above the heat exchange unit (15). The circulation of the fluid which is constituted of a two-phase mixture of water and steam is thus activated, while avoiding drawing out a significant quantity of water with the steam.
