项目摘要

The focus of this project is to understand the utilisation of plasma-assisted surface conditioning of low-iron glass solar reflecting mirrors for concentrating solar thermal power applications. The Global Concentrating Solar Power (CSP) market was valued at over $3 Billion US in 2016 and is anticipated to grow by 13% by 2025. CSP plants generate electricity by concentrating sun light with large arrays of mirrors which are usually located in desert regions. Consequently, the mirrors get covered in sand and dust, and require cleaning with brushes and water on a regular basis. Currently much water is used to clean the mirrors, a precious resource in arid terrains. The aim of this project is to investigate the characteristics of a novel atmospheric pressure plasma system used to condition CSP concentrating mirrors which will be capable of reducing the amount of water used in the cleaning process. There is also a compelling business desire to undertake this project. The development of a novel atmospheric pressure plasma system will be a significant game changer in the CSP market. Such a disruptive technology is anticipated to yield significant commercial benefits.The project will include the following stages within the overall research methodology:Modeling and simulation of the deposition of sand and dust onto mirror surfaces at a variety of different geographical locationsExperimental analysis of sand and dust saltation, erosion, abrasion, and suspension in arid regions within the solar belt (typically within the tropical latitudes).Characterisation of mirror surfaces by interferometry, scanning electron microscopy with energy dispersive x-ray analysis for elemental compositional identification, photogrammetry for shape distortion, reflectometry for specular reflectance, and contact angle measurements to determine surface condition.Investigation of the characteristics to improve the efficiency of a novel atmospheric pressure plasma system for the in situ surface cleaning of mirror surfaces in the presence of water in arid regions.Testing and optimisation of the plasma system for a range of mirror surface types at different CSP locations within the solar belt or at representative test locations within Europe.

该项目的重点是了解等离子体辅助表面处理低铁玻璃太阳能反射镜在聚光太阳能热能应用中的应用。2016年，全球聚光太阳能(CSP)市场价值超过30亿美元，预计到2025年将增长13%。CSP工厂通过利用通常位于沙漠地区的大型反射镜来集中太阳光来发电。因此，镜子上覆盖着沙子和灰尘，需要定期用刷子和水清洗。目前，大量的水被用来清洗镜子，这是干旱地区的一种宝贵资源。本项目的目的是研究一种用于调整CSP聚光镜的新型大气压等离子体系统的特性，该系统将能够减少清洗过程中使用的水量。也有一个令人信服的商业愿望来承担这个项目。一种新型常压等离子体系统的开发将对CSP市场的游戏规则产生重大影响。这种颠覆性技术预计将产生显著的商业效益。该项目将在整个研究方法中包括以下阶段：对不同地理位置的镜面上沙尘沉积的建模和模拟对太阳带内干旱地区(通常在热带纬度内)沙尘的跳跃、侵蚀、磨损和悬浮进行实验分析。通过干涉测量对镜面进行表征，用能量色散X射线分析进行元素成分识别的扫描电子显微镜，用于形状变形的摄影测量法，用于镜面反射的反射法，和接触角测量以确定表面状况。研究提高新型大气压等离子体系统在干旱地区有水存在的情况下就地清洗镜面表面的效率的特性。在太阳带内的不同CSP位置或在欧洲境内的代表性测试地点测试和优化一系列镜面类型的等离子体系统。
