Systems and methods for shielding falling particles within a solar thermal falling particle receiver
| DWPI Title: Solar thermal falling particle receiver, has housing comprising aperture including border surrounding aperture, where aperture receives solar energy into space of housing, and structures protruding from housing proximate to aperture |
| Abstract: Systems and methods for falling particle receivers are disclosed that include shield or deflector structures around the receiver aperture to reduce wind effects and/or heat losses from the falling particles. External and internal structures are disclosed that can be tailored to reduce particle, thermal, and radiative losses from within the cavity receiver due to external wind and the falling particles that are irradiated within the receiver. Structures of varying shapes, sizes, and composition (transparent, reflective) are described. |
| Use: Solar thermal falling particle receiver. |
| Advantage: The receiver improves heat transfer to falling particles by reducing convective and radiative heat losses through use of wind deflectors. The receiver shields the falling particles of the receiver from wind and reduces particle and heat losses through the aperture. |
| Novelty: The receiver (100) has a housing (102) comprising an aperture (106) including a border surrounding the aperture, where the aperture receives concentrated solar energy into interior space of the housing. Structures are attached to and protrude from the housing proximate to the aperture, where the structures are panels (111) adjacent to the border of the aperture, and the structures are a single structure that surrounds the aperture. The structures comprises a reflective surface (110A) including a solar reflectance greater than 50 percentage of incident radiation, where one of the structures protrudes into the interior space, and an orientation of one of the structures is controlled by a sensor and/or control system. |
