Heat exchanger for creating steam for solar power plants

摘要

The heat exchanger has inlet- and outlet collectors (6, 7) for heat-absorbing medium i.e. water, and arranged within an outer casing (2). A meander-like tube bundle (11) has tube layers comprising tubes around which heat-emitting medium completely circulates. The heat exchanger is designed according to forced flow circulation principle so that the heat-absorbing medium is preheated, evaporated and overheated in course of melt flow path, where energy required for preheating, evaporation and overheating is provided by exchange of heat from the heat emitting medium to the heat-absorbing medium.
