A solar radiation absorber element for a thermal concentrating solar power plant is achieved by forming a selective coating on an outer surface of a substrate made from stainless steel, chosen from stainless steels presenting an aluminum content of more than 0.5% by weight. Formation of the selective coating includes a surface treatment step of the substrate, by polishing, and a heat treatment step of the substrate, in an oxidizing atmosphere, in a temperature range included between 550&#xb0; C. and 650&#xb0; C. The heat treatment in particular enables at least one intrinsically selective superficial thin layer to be formed on the outer surface of the substrate.

Process for producing an element for absorbing solar radiation for a thermal concentrating solar power plant

The invention relates to a method of manufacturing a reflector () including a mirror () supported by a support structure (), where the said method includes a step of positioning the mirror relative to the said support structure by moving a mold () supporting the mirror relative to the said structure, According to the invention, the method also includes a step of adjustment of multiple links () between the mirror and the structure, implemented during the step of positioning of the mirror, and/or after this step, and causing at least a proportion of the links to be moved relative to the structure ().

Method for manufacturing a reflector, preferably for the solar energy field

A solar receiver for a thermal power plant including a plurality of absorber modules, each absorber module including at least one face configured to be illuminated by a solar flux, wherein the modules are arranged side by side forming a paving. Each absorber module further includes its own fluid circuit in which a fluid to be heated by the solar flux can flow, the fluid circuits of the absorber modules being connected to one another.

Modular solar receiver and solar power plant comprising at least one such receiver

A seal intended to be inserted between a first and a second member, the seal including: two contact portions spaced from each other along a spacing direction, respectively intended to contact in a tight manner the first and second members, the contact portions being made of a first alloy displaying superplasticity properties under predetermined stress conditions including predetermined temperature conditions, the contact portions being supported by a support arranged therebetween, produced so as to display, under the predetermined temperature conditions, a greater mechanical compression resistance in the spacing direction than that of the contact portions.
