Definitions
- the present invention relates to a covering material for a solar thermal power generation system and a solar thermal power generation system obtained by expanding the same. More specifically, the present invention relates to a coating material for a solar thermal power generation system having excellent mechanical strength, transparency, and weather resistance, and a solar thermal power generation system obtained by extending the same. Background art
- the solar thermal power generation system has a structure consisting of a 4 km-diameter circular heat collector with a chimney 1 km high in the center.
- the heat collecting part has a structure like a greenhouse having no surrounding wall. In this structure, the air heated by the heat collector moves inside the roof of the heat collector toward the center with a high slope, and reaches the highest point in the center. The heated air is sucked into the chimney located in the center of the heat collector. At this time, power is generated by a wind turbine installed in Chimney.
- the temperature inside the heat collecting section is higher than the outside temperature, so even if the solar radiation is shady, the air flow is generated by the heated air in the heat collecting section and the power generation can be continued.
- the heat storage material in the heat collector, the air can be warmed by heat radiation from these heat storage materials even at night, and power can be generated.
- Non-Patent Document 1 describes that a vinyl resin can be used as a coating material used in a solar thermal power generation system. If a material with insufficient weather resistance is used as a covering material for the heat collecting part of the solar chimney, which is intended to supply power almost permanently, periodic replacement is required, and large area heat collecting The cost of replacing the roof will increase. As a result, there is a problem that the power cost increases. In addition, the air heated in the heat collector has a higher wind pressure as it moves to the center. Therefore, when a material having insufficient mechanical strength is used, it is necessary to install the support structures at narrow intervals, and there is a problem that sunlight is blocked by the support structures and power generation efficiency is reduced. On the other hand, in glass having excellent weather resistance and mechanical strength, it is necessary to use a narrow and thick support structure to support the mass of the glass, and there is a problem that sunlight is blocked and power generation efficiency is reduced.
