Estimating the term…
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.
A steam superheater located in the upper part of the vertical housing, including two tube banks of the first and second superheating stages, inlet and outlet headers and nozzles of the steam-in and steam-out, wherein 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.
