  • Multi-stage falling particle receivers
    Patent number: 11846451
    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.
    Type: Grant
    Filed: January 26, 2021
    Date of Patent: December 19, 2023
    Assignees: National Technology & Engineering Solutions of Sandia, LLC, Commonwealth Scientific and Industrial Research Organisation
    Inventors: Clifford K. Ho, Jin-Soo Kim, Apurv Kumar
