A particle receiver includes an inlet, an outlet and multiple tubes rotatably coupled to the inlet and the outlet. The tubes receive particles via the inlet, the particles passing along a passageway of each of the tubes to the outlet. The tubes receive a solar flux as they rotate to heat the particles passing through the tubes. A heat transfer coefficient of the particles is increased by increased mixing via air flowing in the tubes, fins used to mix the particles or via channels via which the particles pass through that increase turnover and mixing of the particles.

Tubular receiver for heating particles with solar energy

A particle suppressor can be used in a particle receiver to reduce the particle loss rate. The receiver can include a rotating drum with an inliner. The particle suppressor can include a retaining surface. The retaining surface can be spaced away from and extend concentrically with the inline. A spacing gap between the inliner and the retaining surface can dampen the motion of bouncing particles. The spacing gap can be between 15 mm and 20 mm. In some embodiments, the particle suppressor can include a support ring with a plurality of suppressor segments disposed circumferentially around the support ring. The particle suppressor can include a plurality of suppressor segments coupled directly to the inliner. A heat shield can be coupled to the particle suppressor. A support bracket can suspend the particle suppressor within the receiver.
