Liquid Metal Cooled Solar Central Receiver Feasibility Study and Heliostat Field Analysis. Part I. Liquid Sodium Cooled Central Receiver System Conceptual Design. Final Report

摘要

A conceptual design for a 100 MWe Solar Tower System employing liquid sodium as a heat transfer fluid and as a storage medium is generated. This design intentionally parallels the current commercial baseline design for a water/steam transfer fluid in order to enhance comparisons between the two approaches and to maximize the application of the limited funds in this study to the unique features of the liquid sodium system. Heat transfer at the receiver and the steam generator were considered in detail. Components for the liquid sodium loop currently under test on development were identified for a 10 MWe pilot plant and a 100 MWe demonstration plant. Economic comparisons with the MDAC water/steam receiver are favorable. (ERA citation 03:026034)
