VOLUMETRIC SOLAR RECEIVER

摘要

A volumetric receiver vessel for heating a fluid with concentrated solar radiation which includes: an external housing having an aperture at the front end; an internal housing separating fluid entering the vessel from fluid exiting thereof; a window covering the aperture of the vessel, where the window closes and seals the aperture of said vessel against a non-metallic seal; and a radiation absorber, located inside the vessel and places to absorb radiation entering the vessel through said window on a radiation absorbing surface, where said surface include at least two zones with different radiation absorption coefficients.

1. A vessel comprising:
an external housing with a front end and a rear end, and having an aperture at the front end; an internal housing separating fluid entering the vessel from fluid exiting the vessel; a window covering the aperture of the vessel; a radiation absorber, located inside the vessel and placed to absorb radiation entering the vessel through said window on a radiation absorbing surface, said surface comprising at least two zones with different respective radiation absorption coefficients on a side of the absorber facing said window; a fluid ingress and a fluid egress in the external housing to, respectively, inject therein or withdraw therefrom a fluid in a manner enabling fluid interaction with the radiation absorber.
