世界各地实施太阳能热电厂的步伐正在加快。在许多情况下，太阳能发电厂安装在干旱地区，尽管有大量的海水，但对饮用水的需求很大。因此，太阳能热电厂与热脱盐装置相结合，用于热电联产和汗水水。伊朗是一个太阳能项目潜力巨大的国家，当然，它正处于严重的水危机之下。设拉子电厂是伊朗正在运行的太阳能热电厂之一。该工厂最近正在进行扩建项目，将与燃气锅炉相结合，旨在使其产能翻一番，同时使其电力输出更加平稳。本研究探讨了电-水联合生产的可行性，在这个案例研究中，基于传统和改进配置的一些创新方法。对所有提出的方案进行了设计、热力学建模和分析。在能源效率和生产率方面对不同的配置进行了比较。结果表明，联合循环通过动力块的冷凝器供热，以及分配给燃气锅炉的热回收装置，优于所有其他可能的配置。在这种情况下，平均效率为10.76%，对于500千瓦的发电厂，每天的淡水产量可能高达852.32吨。
The pace of implementing solar thermal power plants is increasing all around the world. In many cases, solar plants are installed in arid areas with severe demand for potable water despite the large availability of seawater. Thus, the solar thermal power plant is combined with a thermal desalination unit for the cogeneration of electricity and sweat water. Iran is a country with a very strong potential for solar projects, and of course, under an intense crisis of water. Shiraz plant is one of the solar thermal power plants in operation in Iran. The plant has recently gone under an expansion project to be combined with a gas-fired boiler, aiming to double its capacity yet smoothening its power output. This study investigates the feasibility of the co-production of electricity–water in this case study based on a number of innovative methods in conventional and modified configurations. All the proposed scenarios are designed, thermodynamically modeled, and analyzed. The different configurations are compared in terms of energy efficiency and production rate. The results indicate that the combined cycle with heat supply through the condenser of the power block, as well as the heat recovery unit allocated for the gas boiler, outperforms all the other possible configurations. In this case, the average efficiency is 10.76%, and a daily freshwater production as high as 852.32 Tonne per day is possible for a 500 kW power plant.
