Abstract

A joint effort between the Department of Energy and private industry through the Electric Power Research Institute combined various subsystems at the Central Receiver Test Facility (CRTF) in Albuquerque, NM, with a steam generator and a turbine/generator to produce electric power. This effort demonstrates the feasibility of using molten salt as the primary medium for energy transfer from a central tower solar receiver through thermal storage to a steam generator. A conventional steam turbine converts the energy by means of the electric generator for delivery of electrical power to the utility grid. The Molten Salt Electric Experiment (MSEE) uses a 5 megawatt thermal (5MWt) solar receiver, which was successfully tested in 1980, to produce 566 °C (1,050 °F) liquid sodium nitrate‐potassium nitrate (60/40) from a 310 °C (590 °F) feed supply at the rate of 43,900 kg/h (97,000 lbs/hr). (MWt=electrical equivalent of Btu/hr of thermal energy absorbed by a soiar receiver.) The hot molten salt then flows into a sto...
