Abstract
A generator for the production of both superheated steam and saturated steam has an outer casing formed by an inner cylindrical shell engaged within an outer cylindrical shell, the shells being closed by dished ends. An annular header for the admission of pressurized primary water is formed between an upper annular tube plate and a partition-wall while an outlet header for the discharge of primary water is formed by a central tube plate mounted within the inner shell. A bundle of parallel tubes for the circulation of primary water extends vertically upward from the central tube plate. The end portion of each tube has the shape of a crook in order to join the tubes to the annular tube plate in uniformly spaced relation. The secondary water is admitted into the casing by means of ducts formed in the inner shell near the central tube plate. The steam generated is discharged through ducts formed in the outer shell.
