Patent ID: 7024857

Claim:
A solar receiver for receiving solar radiation and converting its energy into another form of energy, the receiver comprising: (a) a housing defining a receiver chamber having a longitudinal central axis and an aperture; (b) a window mounted in said aperature and adapted for the admission of concentrated solar radiation and passing it into said receiver chamber; (c) at least two inlet means axially spaced from said window and positioned at different distances therefrom for the injection into the receiver chamber of different flows of working fluid; (d) an outlet means for the ejection of the working fluid out of the receiver chamber; and (e) absorption control means for the provision of said different flows of the working fluid with different capability to absorb solar radiation such that said capability is higher in the flow of the working fluid adapted for the introduction in said chamber via that one of said at least two inlets which is spaced from said window to a greater distance.
