ABSTRACT:
Solar thermal central receiver systems have been under development since the early seventies. The first central receiver systems used water/steam as a heat transfer fluid in the receiver. Subsequent studies and test programs investigated molten salt, liquid sodium, and hot air as heat

transfer fluids. They all possess certain advantages over water/steam, but many feel that molten nitrate salt is the most promising heat transfer fluid, particularly for utility-scale electric power plants with thermal storage. A complete molten salt system experiment has been built at the Department of Energy (DOE) Central Receiver Test Facility (CRTF) located at Kirtland Air Force Base, Albuquerque, New Mexico. Two of the subsystems, the receiver and the thermal storage unit, have already been built and tested as subsystem research experiments, although the salt loop from the storage tanks to the receiver, consisting of a new boost pump, approximately 400 ft. of piping, valves, surge tanks and supporting instrumentation and control, is all new hardware. The tower and heliostat field are already available to concentrate solar energy onto the receiver. A molten salt steam generator has been designed and built specifically for this experiment. A 750 kWe turbine/generator has been installed to convert thermal energy to electricity. This electricity will be fed into the local power grid. The heat rejection subsystem is part of the CRTF and has been used in previous test programs. The master control subsystem for the complete experiment is new.
