Rotating collector ring for centrifugal solar receiver

A collector ring assembly for a centrifugal solar receiver, the collector ring assembly comprising:

• a collector ring configured to capture particles from the centrifugal solar receiver and reduce a speed of the particles, the collector ring comprising a plurality of shovels arranged circumferentially about a central longitudinal axis of the collector ring, each of the plurality of shovels comprising:
• a front wall;
• a bottom wall extending from the front wall;
• and
• a rear wall extending from the bottom wall, wherein the front wall, the bottom wall, and the rear wall define a trough configured to collect particles;
• and
• a stationary shroud disposed around the collector ring, the stationary shroud configured to collect and funnel particles exiting from the collector ring, the stationary shroud comprising a pointed top shelf and a stepped bottom shelf.

A collection member of a collector ring for a centrifugal solar receiver, the collection member comprising:

• a front wall;
• a bottom wall extending from the front wall;
• a rear wall extending from the bottom wall, the rear wall comprising a wide portion and a narrow portion, wherein the front wall, the bottom wall, and the rear wall define a trough configured to collect particles;
• an angled shield extending from the front wall, the angled shield comprising an angled surface, wherein the angled shield is configured to direct particles into the trough;
• a lateral lip extending from the front wall, wherein the lateral lip is configured to capture particles that travel past the angled shield and direct those particles into the trough;
• and
• a top wall extending from the front wall.
