Embodiment Construction
[0046] exist figure 1 A linear concentrated solar power plant is schematically shown in .
[0047] The linear concentrating solar power plant 1 comprises a solar cell array 3 in which a heat transfer medium is heated by incident solar radiation 5 . To achieve this, the solar array 3 generally comprises a plurality of receivers connected in series, through which the heat transfer medium is guided. The receiver in any case comprises a plurality of mirrors in which the incident solar radiation 5 is concentrated and redirected onto the heat transfer medium. In this case, the mirror can be designed, for example, in the form of a parabolic trough mirror or a Fresnel mirror.
[0048] The heat transfer medium usually flows out of the solar cell array 3 and first enters the heat storage tank 7 of the heat storage system 9 . The heat transfer medium flows out of the thermal storage tank 7 and into the heat exchanger 11 where it transfers heat to the water circuit. The water in the w...

The invention relates to a method for operating a linear concentrator solar power plant (1), in which method a heat exchange medium flows through a pipeline loop (47) with at least one receiver, wherein the heat exchange medium has a flow velocity which is so great that the flow in the pipeline loop (47) is turbulent, wherein at least part of the heat exchange medium is removed upon exit from the pipeline loop (47) and is guided back into the pipeline loop (47). Furthermore, the invention relates to a linear concentrator solar power plant having at least one pipeline loop (47) with at least one receiver, in which a heat exchange medium which flows through the pipeline loop (47) is heated by incoming solar energy, wherein a mixing device (27) is included, in which at least part of the heat exchange medium which flows through the pipeline loop (47) is mixed with heat exchange medium to be fed in.
Description
technical field [0001] The invention relates to a method for operating a linear concentrating solar power plant, in which a heat transfer medium flows through a pipeline loop with at least one receiver, the heat transfer medium having such properties that impermissible forces do not occur within the pipeline loop Flow rate of temperature difference. This is usually obtained because the flow in the pipeline loop is turbulent. Furthermore, the invention relates to a linear concentrated solar power plant having at least one pipeline loop with at least one receiver, wherein a heat transfer medium flowing through the pipeline loop is heated by solar radiation. Background technique [0002] A linear concentrating solar power plant is, for example, a parabolic trough solar power plant or a Fresnel solar power plant. These power plants typically include multiple loops of piping through which a heat transfer medium flows. The pipeline loop is equipped with a receiver in which the ...
