Abstract

Solar energy has a great potential in many areas of industrial activity in Algeria. This is because most of Algeria has high levels of sustainable solar insulation. Unfortunately, few industries use solar energy for hot water generation, but some industrial processes require hot water at temperatures that can be easily obtained from solar thermal panels. This paper presents a case study to investigate the technical and financial feasibility of a solar-powered industrial agro-processing system in Algiers. Based on  the solar collectors connection type for which the economic feasibility study was carried out, an appropriate design of the system was determined. The latter was actually done by analyzing the levelized cost of energy savings. The design of the thermo-solar process is carried out based on F-chart method with a new approach by integrating the incidence angle modifier and of using real and experimental data requirements to determine realistic achievable performance of the solar process. The results showed that, in comparison to the currently used electrical system, the electrical energy savings achieved by the solar-powered system make it an economically viable option with a solar coverage rate of 80%. The investment depreciation balance shows that the use of such a thermal solar energy system will be more competitive than fossil fuels system if the price of electricity in the country increases from 0.048 to 0.075 €/kWh.

阿尔及利亚工业低温热水生产系统的设计、优化和经济可行性:一个案例研究
太阳能在阿尔及利亚的许多工业活动领域具有巨大潜力。这是因为阿尔及利亚大部分地区都有高水平的可持续太阳能隔热。不幸的是,很少有行业使用太阳能发电,但一些工业过程需要的热水温度可以很容易地从太阳能热板中获得。本文介绍了一个案例研究,以调查阿尔及尔太阳能工业农业加工系统的技术和财务可行性。根据进行经济可行性研究的太阳能收集器连接类型,确定了系统的适当设计。后者实际上是通过分析能源节约的平准化成本来完成的。热太阳能过程的设计是基于F图方法进行的,这是一种新的方法,通过集成入射角修正器,并使用实际和实验数据要求来确定太阳能过程的实际可实现性能。结果表明,与目前使用的电力系统相比,太阳能系统节省的电能使其成为一种经济可行的选择,太阳能覆盖率为80%。投资折旧余额表明,如果该国的电价从0.048欧元/千瓦时提高到0.075欧元/千瓦小时,那么使用这种太阳能热能系统将比使用化石燃料系统更有竞争力。
