Abstract
A bundle of J-shaped tubes uniformly spaced in radial planes about the axis of a cylindrical shell is provided for the circulation of a primary fluid between on the one hand an inlet header delimited by a central tube plate and by the top dished end of the shell and on the other hand a toric outlet header which is partly delimited by the peripheral tube plate and the shell wall and is located above an annular space between the shell wall and a coaxial inner skirt. At least one nozzle for the supply of secondary fluid in the liquid state opens into the annular space and a lateral chamber is formed within the shell between the primary fluid inlet and outlet headers for collecting the secondary-fluid steam produced in contact with the tubes.
