    • A heat exchanger erected vertically for generating steam for solar power plants, including: an outer casing with an inlet and an outlet port for a heat-emitting medium; an inlet and an outlet collector for a heat-absorbing medium, said inlet and outlet collectors lying substantially within the outer casing; and a tube bundle within the outer casing with a number of tube layers including continuous tubes, wherein the heat-emitting medium can flow entirely around same and which are designed as flow paths for the heat-absorbing medium from the inlet collector to the outlet collector. The tube bundle is arranged in a meandering manner, wherein the heat exchanger is arranged according to a forced-flow principle so that the heat-absorbing medium is successively pre-heated, evaporated, and superheated so that a superheated steam exits the outlet collector. The energy for the pre-heating, evaporation, and superheating is essentially provided by the heat transfer from the heat-emitting medium to the heat-absorbing medium. The tube layers are arranged in such that the tubes of the individual tube layers are aligned to lie next to one another in the horizontal direction, with the directions of flow of the heat-absorbing medium being opposite in the horizontally adjacent tube sections which are arranged transversely to the central axis of the outer casing, and such that the tube layers are vertically adjacent. Each tube layer is formed from an equal number of tubes.
    • 一种垂直竖立用于产生用于太阳能发电厂的蒸汽的热交换器,包括:具有用于发热介质的入口和出口的外壳; 用于吸热介质的入口和出口收集器,所述入口和出口收集器基本上位于外壳内; 以及在外壳内的管束,其具有包括连续管的多个管层,其中发热介质可以完全流动相同,并且被设计为用于吸收介质从入口收集器到出口收集器的流动路径 。 管束以曲折的方式布置,其中热交换器根据强制流动原理布置,使得吸热介质被依次预热,蒸发和过热,使得过热蒸汽离开出口收集器。 用于预热,蒸发和过热的能量主要通过从发热介质到吸热介质的热传递来提供。 管层被布置成使得各个管层的管子在水平方向上彼此相邻地对准,其中吸热介质的流动方向在布置的水平相邻的管部分中相反 横向于外壳的中心轴线,并且使得管层垂直相邻。 每个管层由等量的管形成。
