Abstract

This chapter reviews new solar thermal receiver designs to achieve higher temperatures for higher-efficiency power cycles and high-temperature thermochemical processes. Direct particle receivers include free-falling, obstructed-flow, centrifugal, and fluidized designs that irradiate the particles directly. Advantages include the potential for high efficiencies due to direct irradiance of the heat transfer media. Challenges include reducing particle and heat losses through the open aperture. Indirect particle receivers ...
