Abstract
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.

1-19. (canceled)
A solar receiver with a longitudinal axis, comprising:
- an absorber;
- a bearing structure extending over an entire length of the solar receiver and configured to suspend the solar receiver in a solar power plant,
- a protection structure mounted around the bearing structure forming an envelope around the bearing structure,
- the protection structure configured to protect the bearing structure from heating due to solar flux,
- the bearing structure and the protection structure configured to slide with respect to each other along the longitudinal axis, the absorber extending longitudinally.
A solar power plant of Fresnel type, comprising:
- a solar receiver with a longitudinal axis comprising an absorber, a bearing structure extending over an entire length of the solar, a protection structure mounted around the bearing structure forming an envelope around the bearing structure, the protection structure configured to protect the bearing structure from heating due to solar flux, the bearing structure and the protection structure being configured to slide with respect to each other along the longitudinal axis, the absorber extending longitudinally;
- a frame from which the receiver is suspended above mirrors;
- suspension means connecting the bearing structure of the frame;
- a circuit supplying cold heat transfer substance to an inlet of the absorber;
- and
- a circuit collecting hot heat transfer substance connected to an outlet of the absorber.
