Fluid selection for a 100 MW/e/ line focus solar central power station
Abstract
System point designs have been prepared for three fluids, including Therminol 88, draw salt (a 50% molar mixture of potassium nitrate and sodium nitrate), and sodium. The following qualitative and quantitative factors have been considered: capital cost, operation cost, cost uncertainties, development requirements, design flexibility, design credibility and marketability, reliability, and availability. Draw salt has been selected for the heat transport fluid based principally on projected system cost and acceptability. The problem of draw salt freeze up, which is the most significant operational problem, can be solved by heat tracing, proper piping system design, and proper system drainage.
