SOLAR POWER TOWER RECEIVER

摘要

A central receiver for a solar power facility is provided comprising an arrangement of heat absorber tubes located in a chamber having a window that, in use, is to receive solar radiation reflected by a heliostat field. The heat absorber tubes extend transversely relative to the window and are connected into a working fluid circuit. The window forms an atmospheric air inlet and the chamber has an outlet in a region opposite the window. An air flow promoting fan induces a flow of atmospheric air inwards through the window, past the absorber tubes; and through the outlet. The receiver preferably includes multiple rows of unpressurized louvers or panes having oblique frontal surfaces such that reflected rays travel into the chamber and provide a leading row in which the temperature of the louvers is, under operating conditions, maintained at a level low enough to reduce thermal reflection and radiation losses.
