Abstract
The present disclosure is directed to multi-stage falling particle receivers and methods of falling particle heating. As the particles fall through the receiver, the particles are periodically collected and released by flow retarding devices. The periodic catch-and-release of the particles falling through the receiver reduces particle flow dispersion, increases particle opacity and solar absorption, and reduces erosion and damage to surfaces caused by direct particle impingement.
Claims21
A solar receiver, comprising:
- a housing comprising at least one opening for receiving concentrated solar irradiance and a front wall and a rear wall;
- one or more openings in the housing for receiving irradiance;
- and
- a flow retarding system comprising one or more flow retention devices disposed within the housing for receiving, accumulating and releasing particles as the particles fall through the solar receiver.
A falling particle solar heating method, comprising
- providing particles to a solar receiver;
- and
- collecting, accumulating and releasing particles in one or more flow retarding devices as the particles fall through the solar receiver and are heated by solar irradiance.
