Claim 15:
16. A solid particle receiver configured to receive solid particles in a solar central receiver system, the solid particle receiver comprising:
an inlet portion forming a passageway sized to receive a stream of solid particles;
an outlet portion forming a passageway sized to transmit the stream of solid particles;
a solid particle passageway between the inlet portion and the outlet portion; and
a porous structure having a top face to receive the stream of solid particles and a front face to receive solar radiation, wherein the porous structure is in the solid particle passageway between the inlet portion and the outlet portion and is configured to transmit the solid particles throughout the porous structure, the porous structure having a porosity that impedes movement of the stream of solid particles during downward travel from the inlet portion to the outlet portion; wherein the inlet portion is above the outlet portion so that the stream of solid particles falls down, under the force of gravity, through the porous structure, and wherein the porous structure has ligaments that facilitate dispersion of the solid particles through the porous structure between the inlet portion and the outlet portion.
