Název projektu:
New solar reflector for concentrating solar- thermal power (10 ES 27F4 3JH5)
Popis:
An Andalusian new technology based SME has developed a new solar reflector for concentrating solar- thermal power plants of any technology. It replaces the existing, providing a significant technical development on them. Its main advantages are the strong reduction of the high cost, lower manufacturing times and increased performance. It can be mounted on existing plants and presents a considerable reduction in weight and easy assembly. They are open to several kind of collaboration
Požadavky na partnera:
The objective of the research and innovation has been to achieve the reduction of strong investments required in the existing solar thermal power plants, applying technological improvements, reducing costs and maintaining the same performance or increasing it.
The company, with this project focused on concentrating solar-thermal power field, bet clearly on achieving these goals. For that, they want to achieve the highest use of solar radiation in a simple and economical way, and therefore improve the profitability of this solar application. This purpose is possible, in part, thanks to a new solar reflector, one of the main components of thermal power plants. This reflector replaces the existing ones and can be coupled to current collectors of different technologies, with the same optical definition or a new one, without changing its structure and assembly.
Problems and aspects to improve of the current reflectors:
- Loss of efficiency and reflectivity, dust and wind make rough the glass surface (exterior surface quality, polished and tension of reflection area, resistance to abrasion of the time, the chemical composition of glass must be low in iron).
- The inside surface, where the silver sheet is stuck or glued, must be tense and accurately respond to the chosen optical definition.
- Optimization of Operation and Maintenance work.
- Reduction of weight for best assembly (manual).
- Difficulty in maintaining appropriate theoretical optical definition (large parts, weak and subject to sudden changes in temperature). The ceramic fixings do not allow future regulation.
- High costs of manufacturing and assembly.
The new reflector tries to achieve substantially the following:
" Replace the current reflectors, applied to any solar- thermal technology, without changing fundamental aspects, such as optical definition, method of fixing, structure in which they are fixed, etc." Replace the current, with modification of the current optical definition; even if it is necessary retouch the fixings and support structure, in order to " Open new lines of research of new collectors and new related products.
The aspects described above are possible since the new reflector is not made of glass, but cheaper and versatile plastics materials than the current employees. This, added to its manufacturing method fully automated and with very experienced industrial processes, can achieve very short production cycles. The direct consequence of the results indicated is a significant savings in manufacturing costs. It is estimated an initial reduction of the current sale price of 40%, keeping the profit margin per reflector.
The strong design or conception of the new reflector ensures dimensional stability, independently and at the time of mounting the support structure, ensuring no change in the optical definition, key issue for performance. Besides, if it comes to it, the new reflector would allow the reduction of the absorber tube's diameter and the elimination of the glass tube that surrounds it.
Assembly and placement of the new reflector, in the theoretical position required, can be carried out automatically with adjustable precision. The new reflector can be replaced much earlier, due to their lower cost and it is not disposable, REUSE capacity at a price below the original. In addition, the theoretical position when mounted in the structure can be verified and corrected periodically in a fully automatically way. This corrective action is ensuring efficiency as time goes, very important aspect and currently not carried out.
With respect to new lines of investigation include: the execution of new reflectors, with new designs for parabolic trough plants, which can increase performance, so that would come to increase the productivity of existing plants of 50 MW or to reduce its size substantially. For plants with Stirling discs (reflectors paraboloids of revolution) could be obtained multiplying the performance (of the current unit) or greatly reduce its size. In both cases, the reflectors are already designed.
Innovative Aspects:
1. Made of plastic material (nowadays made of glass)
2. Automatic mass production (now semi-automatic)
3. Reduction in the costs of manufacturing of the reflector (40% initially estimated on current sale price. Therefore, this would mean a reduction of costs on reflectors between 5 and 8 million Euros for every 50 MW.)
4. More efficient than the current.
5. More resistance to external agents, with less affectation on the performance of the reflector.
6. Non-disposable and reusable at a cost lower than the initial manufacturing.
7. Automatic assembly, including best-fit over the support structure.
8. As the reflector is not broken, periodic maintenance and adjustment is greatly improved.
9. Complete design, guaranteed industrialization.
10. After validation of prototype phase, the set-up is done before starting the mass production stage.
