Abstract

This chapter presents new possibilities for linear Fresnel reflector (LFR) solar power plants using superheated steam, molten salts, and other heat transfer fluids (HTF). The main idea is to increase the working temperatures up to 540 °C in order to achieve higher solar-electricity efficiency conversion using a conventional Rankine cycle. In this sense, this chapter presents the current state of the art regarding the usual HTFs used in practice, the schematic configurations operating with molten salts as HTF, and a calculation of the total ...
