GLASS TUBE WITH AN ANTIREFLECTIVE LAYER WITH A COMPOSITE MATERIAL, METHOD FOR MANUFACTURING THE GLASS TUBE, HEAT
RECEIVER TUBE WITH THE GLASS TUBE AND SOLAR COLLECTOR WITH THE HEAT RECEIVER TUBE
BACKGROUND OF THE INVENTION 1. Field of the invention
This invention relates to a glass tube, a method for manufac¬ turing the glass tube, a heat receiver tube with the glass tube and a solar collector with the heat receiver tube.
2. Description of the related art
A solar collector (sun energy collecting unit) of a sun field power plant based on the concentrated solar power technique is for instance a parabolic trough collector with parabolic mirrors and a heat receiver tube. The heat receiver tube is arranged in a focal line of the mirrors. By sunlight reflect¬ ing surfaces of the mirrors the sunlight is focused to the heat receiver tube. The heat receiver tube comprises a core tube, which is filled with a heat transfer fluid, e.g. a thermo-oil or molten salt. Via the core tube of the heat re¬ ceiver tube the energy of the sunlight is coupled into the heat transfer fluid. Solar energy is converted to thermal en¬ ergy .
In order to minimize a loss of thermal energy, the heat re¬ ceiver tube comprises an encapsulation out glass (glass tube) . The glass tube, which is transparent for the sunlight, is arranged coaxially around an inner, central stainless tube of the heat receiver tube. The space between the inner tube and the glass tube is evacuated.
A transmission of the glass tube for sunlight has to be as high as possible. In contrast to that, a reflectivity of the glass tube for sunlight has to be as low as possible. For these characteristics an anti-reflective layer (coating) is attached to a glass tube surface of the glass tube. SUMMARY OF THE INVENTION

Preferably for the attaching of the anti- reflective layer at least one colloidal silica suspension with particles with different optical densities is used. Additionally a heat receiver tube for absorbing solar energy and for transferring absorbed solar energy to a heat transfer fluid, which can be located inside a core tube of the heat receiver tube, is provided. The core tube comprises a core tube surface with a solar energy absorptive coating for ab- sorbing solar absorption radiation of the sunlight. The core tube is enveloped by an encapsulation with the glass tube.

Moreover a solar collector is provided comprising at least one mirror having a sunlight reflecting surface for concentrating sunlight in a focal line of the sunlight reflecting surface and at least one heat receiver tube, which is ar- ranged in the focal line of the mirror.
Preferably the solar collector is a parabolic trough collec¬ tor, wherein the mirror is a parabolic mirror. Alternatively, a solar collector with linear Fresnel technology can be realized. So, a linear Fresnel mirror collector with at least one Fresnel mirror having a sunlight reflecting surface for concentrating sunlight in a focal line of the sunlight reflect¬ ing surface and at least one heat receiver tube, which is ar¬ ranged in the focal line of the Fresnel mirror. A glass tube wall of the glass tube is transparent for a wide wavelength range of the rays of the sun. Preferably the glass tube wall of the glass tube comprises glass (SiOx) . Other transparent materials are possible, too. The component materials can comprise different base materials or an equal base material. Preferably the component materials are based on silica. By that measure a temperature induced mismatch between the component materials and/or between the component materials and the glass material of the glass tube is reduced.
In a preferred embodiment the anti-reflective layer comprises an anti-reflective layer thickness which is selected from the range between 50 nm and 300 nm.
Preferably the anti-reflective comprises an anti-reflective layer transmission for sunlight radiation which is more than 92% and preferably more than 94%.

DETAILED DESCRIPTION OF THE INVENTION Given is a glass tube 1 with a glass tube surface 11 which is at least partially covered by an anti-reflective layer 12 (Figure 1) . The anti-reflective layer 12 comprises a compos¬ ite material 122 with two component materials with different optical densities. The anti-reflective layer thickness is about 100 nm thick.
For the manufacturing of the glass tube following steps are carried out: a) Providing a glass tube with an uncovered glass tube surface and b) Attaching the anti-reflective layer onto the glass tube surface. For the attaching of the anti- reflective layer a colloidal suspension with particles with different optical densities is used. The optical densities are 0.50 and 0.85. A volumetric portion of the different par¬ ticles ranges from 10% to 50%.
Following experiment has been carried out: Raw materials of the two component materials are mixed together. After the mixing a borosilicate glass is dipped in. A resulting average transmittance is 97.05 %. For comparison: Carrying out the same experiment for each of the raw materials results in an average transmittance of 96.60%.
The core tube 21 of the heat receiver tube 2 which is envel¬ oped by the glass tube 1 is made of steel. Additionally the core tube surface of the core tube comprises an absorptive coating for absorbing sunlight (not shown) .
The heat receiver tube 2 is part of a solar collector 1000. The solar collector is a parabolic trough collector (Figure 2) . The parabolic trough collector 1000 comprises at least one parabolic mirror 3 with a sunlight reflective surface 31. By the reflective surface 31 sunlight is concentrated in the focal line 32 of the parabolic mirror 3. The concentrated sunlight is absorbed by the heat receiver tube 2.
The parabolic trough collector (and the Fresnel mirror col¬ lector, respectively) is used in a solar power plant for converting solar energy into electrical energy. The heated heat transfer fluid is used to produce steam via a heat exchanger. The steam is driving a turbine, which is connected to a gen¬ erator. The generator produces current.
