International Classification:

F24J 2/46
F24J 2/52

US Classification:

126569

Abstract:

A solar power plant includes central receiver modules arranged in a regular pattern. Each central receiver module includes a tower, a central receiver mounted on the tower, and a heliostat array bounded by a polygon. The heliostat array includes heliostats with mirrors for reflecting sunlight to the central receiver. The heliostats are grouped in linear rows and each of the rows is parallel to another row. The locations of the heliostats are staggered between adjacent rows. The power plant also includes a power block for aggregating power from the central receivers and power conduits for transferring power from the central receivers to the power block.

Abstract:

A system for regulating the temperature and flow rate of a heat transfer fluid for use in a hybrid steam-generating plant is described. A bypass section may be incorporated into the piping network of a primary steam-generating source to route heat transfer fluid from a hot source to a mixer downstream of at least one heat exchanger. Heat transfer fluid from the hot source may be mixed with cooler heat transfer fluid exiting the heat exchanger in the event that the supply from a secondary steam-generating source is lost or becomes intermittent. The result is a system that maintains a constant flow rate of heat transfer fluid through the heat exchangers while minimizing adverse temperature gradient effects that may result from steam production variability and plant operation outside of design point parameters.
