Produce superheated steam for industrials process has been presented as one of the main advantageous applications of Concentrated Solar Power (CSP) plants particularly Linear Fresnel Concentrator (LFC). LFC belongs to this category and produces either steam or hot liquid by concentrating sunlight and converting it to energy. This technology has shown great potential with regard to its integration into several industrial processes including cooling, enhanced oil recovery (EOR), agro-food processes, etc. Nevertheless, despite the growing interest of the scientific and industrial community to this technology, the majority of studies have been focused on the Levelized Cost of Electricity (LCOE) estimation and there is still lack of a clear technology economic competitiveness demonstration at a relevant scale. Aiming to take one step forward in the cost-effectiveness of LFC according to the Direct Normal Irradiation (DNI) level and the fossil fuel price, this work assesses the economic competitiveness of solar boiler based on Fresnel technology and devoted to producing heat for industrials requiring saturated or overheated steam and operating at medium temperature i.e. up to 200 °C: a research area that has rarely been tackled so far. To achieve this purpose, the total payback period has been simulated for several scenarios: industrials already working with a fossil fuel boiler and industrials looking for a new steam production system, and eventually, without Thermal Energy Storage (TES) system and with 2 h of TES system. LFC total payback period has been subsequently compared, with boilers already existing in the market e.g. Heavy Fuel Boilers, Diesel Boilers, etc. Results from the study have shown that LFC could be an excellent alternative to boilers existing in the market and that the payback period is conditioned by DNI level and varies between 2 and 9 years depending on the chosen scenario and the climatic conditions.

生产用于工业过程的过热蒸汽已成为集中式太阳能发电厂（CSP）尤其是线性菲涅尔集中器（LFC）的主要优势应用之一。LFC属于这一类别，它通过聚集阳光并将其转化为能量来产生蒸汽或热液体。在集成到包括冷却，提高采油率（EOR），农业食品加工等多个工业过程的过程中，该技术显示出巨大的潜力。尽管如此，尽管科学界和工业界对该技术的兴趣日益浓厚，研究集中在平均电费（LCOE）估算，仍然缺乏在相关规模上清晰的技术经济竞争力证明。为了根据直接正常辐射（DNI）水平和化石燃料价格在LFC的成本效益方面迈出一步，这项工作评估了基于菲涅尔技术的太阳能锅炉的经济竞争力，并致力于为需要饱和或过热的蒸汽，并在中等温度（即高达200°C）下运行：这是迄今为止很少涉及的研究领域。为实现此目的，已针对几种情况模拟了总投资回收期：已经使用化石燃料锅炉的工业和正在寻找新的蒸汽生产系统的工业，最终没有热能存储（TES））系统和2小时的TES系统。随后将LFC的总投资回收期与市场上已有的锅炉（例如重油锅炉，柴油锅炉等）进行了比较。研究结果表明，LFC可以替代市场上现有的锅炉，并且投资回收期根据DNI级别而定，取决于选择的方案和气候条件，其变化范围为2到9年。
