A solar absorber body for a concentrating solar power system, said solar absorber body including: a tube, designed to contain a heat transfer medium and including a first part designed to be exposed to the sunlight and a second part designed to be unexposed to the sunlight, an assembly of fins made of thermally conductive material, and a selective coating arranged at least on the outer surface of the first part of the tube, said assembly of fins defining at least two longitudinal passages inside the tube, said passages being adjacent in a sectional plane perpendicular to the longitudinal axis of the tube, said assembly of fins being configured to create a continuous thermal bridge inside the tube from at least a portion of the inner surface of first part of the tube to at least a portion of the inner surface of the second part of the tube.

Solar absorber body for a concentrating solar power system and a method for manufacturing a solar absorber body

A solar receiver with a longitudinal axis, including an absorber, a beam extending over an entire length of the solar receiver and configured to suspend the receiver in the power plant, a protective envelope mounted around the beam and including a thermal insulator surrounding the beam, the protective envelope configured to protect the beam from heating due to solar flux, the beam and the protective envelope configured to slide one with respect to the other along the longitudinal axis.

Longer-life solar power plant receiver

A receiver module for a solar power station receiver, including a metal structure and an absorber module, the metal structure defining a cavity extending along a longitudinal axis in a base of which the absorber module is housed. The cavity includes an aperture configured to be aligned towards at least one mirror of the solar power station, the aperture is edged by two side portions of the metal structure extending longitudinally on either side of the cavity. The receiver module also includes thermocouples positioned on each of the side portions relative to the longitudinal axis to detect a temperature difference between a reference temperature and two points of the metal structure that are opposite relative to the longitudinal axis.

The invention relates to a heat exchanger comprising a supercritical carbon-dioxide circuit comprising a plurality of tubes (). The heat exchanger is original in that at least one section of the tubes () have surface irregularities () on their inner surface. These irregularities () are located within a zone () extending as far as a point located at a distance from the inlet () of the tube of maximum 400 times the diameter of the tube.
