HEAT STORAGE DEVICES FOR SOLAR STEAM GENERATION, INCLUDING RECIRCULATION AND DESALINATION, AND ASSOCIATED SYSTEMS AND METHODS

摘要

Heat storage devices for solar steam generation, including recirculation and desalination, and associated systems and methods are disclosed. A representative method includes directing a high temperature working fluid (a) from a thermal storage device to a solar field to heat the high temperature working fluid, and (b) back to the thermal storage device. The method can further include directing a first portion of the high temperature working fluid from the thermal storage device through a first branch of a high temperature working fluid loop to transfer heat to a process fluid at a first temperature. A second portion of the high temperature working fluid is directed from the thermal storage device through a second branch of the high temperature working fluid loop, in parallel with the first branch, to transfer heat to the process fluid at a second temperature less than the first temperature.
