STEAM GENERATOR Russian patent published in 2024 - IPC F22B1/02 F22B19/00 

FIELD: steam generators.

SUBSTANCE: steam generator comprises a prefabricated structure intended for transfer of heat energy removed from the core of the nuclear reactor by the coolant of the first circuit to the working medium of the second circuit. Superheated steam produced at the steam generator (SG) outlet is used further for transformation of thermal energy into mechanical energy, and then into electrical energy. Steam generator comprises a housing in the form of a vertical cylindrical chamber, an elliptical bottom, a cover, a primary coolant supply-discharge branch pipe, an internal device, inlet feed pipe and steam outlet branch pipe located in steam generator cover, steam generator pipe system, pipe sheets for pipe system attachment, inner and outer cylindrical screens, feed sections closed to feed chamber and located under steam generator cover, steam sections arranged above the pipe system, a collecting chamber of superheated steam, displacer located in central area of internal screen, gas removal system.

EFFECT: improving thermal-hydraulic efficiency and resource indices of internal device of steam generator.
