Abstract

Concepts for solar thermal power systems are based on parabolic trough, tower or parabolic disks either heating molten salts, mineral oil, and air or generating steam. In this research work we propose, a new design approach of a solar steam generator/boiler. We have used a design tool here for optimization of system efficiency considering different subsystem efficiency. This concept comes from the conventional thermal power plants boiler, with the difference that the heat comes from mirrors that concentrate the solar radiation on its external absorbing side at open air, instead of fuel flames heating its internal tube grid. The results of our conceptual design show how much plant performance is achievable, comparable with the most advanced solar concepts. From analysis of this innovative solar boiler applied to electricity production, it is found that overall efficiency of the conversion from direct solar irradiation energy to electricity is above 20%, which is comparable to the value of parabolic trough and central tower technologies. With best of our knowledge, no one has reported this kind of work.

概念太阳能热蒸汽发生器的新方法及其设计与优化

太阳能热发电系统的概念是基于抛物面槽、塔或抛物面盘加热熔盐、矿物油和空气或产生蒸汽。在本研究中，我们提出了一种新的太阳能蒸汽发生器/锅炉的设计方法。我们在这里使用了一个设计工具来考虑不同子系统的效率来优化系统效率。这个概念来自传统的热电厂锅炉，不同的是，热量来自于镜子，集中太阳辐射在其外部吸收面在露天，而不是燃料火焰加热其内部管网格。我们的概念设计结果表明，与最先进的太阳能概念相比，工厂的性能是可以实现的。通过对该创新太阳能锅炉应用于发电的分析，发现太阳直接辐照能量转化为电能的整体效率在20%以上，与抛物线槽和中心塔技术的价值相当。据我们所知，还没有人报道过这种工作。
