PERFECCIONAMIENTOS EN GENERADORES DE VAPOR.

摘要

A pressurized-water coolant nuclear reactor steam generator has a vertical housing for the steam generating water and containing an upstanding heat exchanger to which the pressurized-water coolant passes and which is radially surrounded by a guide jacket supporting a water separator on its top. By thermo - siphon action the steam generating water flows upward through and around the heat exchanger within the guide chamber to the latter's top from which it flows radially outwardly and downwardly through a down draft space formed between the outside of the jacket and the housing. The water separator discharges separated water downwardly. The housing has a feed water inlet opening adjacent to the lower portion of the heat exchanger, providing preheating of the introduced feed water. This preheated feed water is conveyed by a duct upwardly to a location where it mixes with the water discharged from the water separator.
