摘要： 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.

摘要： A method and a device for generating superheated steam from a working medium, which includes the following steps: feeding of a working medium in the liquid phase to a specific heating tube and temperature regulation of the specific heating tube. Furthermore, the specific heating tube is temperature-regulated with a defined amount of thermal energy, as a result of which superheated steam is formed in the specific heating tube from the working medium fed in the liquid phase, the superheated steam then departing from the specific heating tube.

摘要： A continuous steam generator including a combustion chamber with a plurality of burners for fossil fuel is provided. A vertical gas duct is connected downstream of the combustion chamber on the hot gas side, in an upper region via a horizontal gas duct. The outside wall of the combustion chamber is formed from evaporation pipes which are welded together in a gas-tight manner and mounted upstream of a water separator system on the flow medium side and from superheater pipes which are welded together in a gas-tight manner and mounted downstream of the water separator system. The water separator system includes a plurality of water separation elements, each element includes an inlet tube which is connected to the respective upstream evaporation for tubes, which extend into a water evacuation tube. A distributer element is arranged on the evaporator side between the respective water separator element and the inlet collector.
