The invention relates to energy, in particular for the system of separation and superheating of steam for nuclear power plant turbines. The invention is aimed at solving the problem of reducing the mass and dimension parameters while maintaining the efficiency of heat exchange.

The task in the claimed invention is solved by the fact that both tube banks of the first and second superheating stages are rotated vertically at the same height in such a way that they form between them and the inside of the housing two segmental inlet headers, a wedged outlet header with an angle of turn from 10 to 90, and the steam outlet nozzle is located in a vertical case opposite the wedged outlet header. The actual reduction in mass and dimension parameters is 18-25%, which allows using this solution in compact systems for steam separation and superheating.

An apparatus is provided for protecting from freezing an above-ground conduit outlet on an exterior wall of a building, the freeze protection apparatus comprising a housing including a top wall, a front wall, and a pair of opposed side walls interconnecting the top wall and the front wall. The housing partially defines an enclosed area having a rear aperture and a bottom aperture. Thermal insulating material lines the interior surface of the walls of the housing. Means are provided for mounting the housing to the exterior wall adjacent the conduit outlet. The inner edges of the side walls and the top wall contact the exterior wall and the bottom edges of the side walls and the front wall contact the ground for enclosing the conduit outlet. Heat is retained within the housing to prevent fluid within the conduit from freezing.
