Central recever tower steam generaor Electricity Cooling s等 Cold feedwater 20ftx 20ft A schematic view of a 1OMWe solar-thermal power plant near Barstow, California. The receiver and boiler that absorb the sunlight reflected from 1900 heliostats are at the top of a 90 meter tower. The heliostats are each steered by computer control to reflect the sunlight onto the receiver. The steam from the boiler can be either delivered directly to the turbine and generator or to storage. The storage system can provide steam for 4 hours of generation at a level of 7MWe without sunlight.
