ABSTRACT:
A solar thermal electric energy system utilizes a solar receptor having a double paned glass window with cooling liquid circulating therethrough. This serves as a window for a solar heat receptor cavity having a number of water or steam carrying tubes therein. A portion of the tubes operate at a temperature range suitable for heating boiler water and another portion of the tubes is at a higher temperature which serves as steam superheat. The liquid flowing through a pair of window panes is triethylene glycol and in addition to cooling the window has an index of refraction which matches the window to provide the most efficient conduction of solar energy to the heat recepting tubes behind the window. The power plant itself includes heat saving jackets around the steam headers to provide for boiler feed water preheat and has both high pressure and low pressure turbines to utilize most efficiently the water being heated by the solar receptors.
