Abstract The use of sustainable energy resources is indispensable nowadays. This paper studies a new solar chimney plant for electrical power generation and water distillation. The operating mechanism of the power plant is based on evaporating seawater using concentrated solar power techniques. The novelty of the proposed system is using steam only as working fluid; also, the collector area is separated away from the solar chimney. The solar field absorbs and transfers solar energy into the steam generator. As steam passes through the chimney, the vapor exchanges the heat with the outside environment resulting in water condensation at the inner surface of the chimney. A set of equations have been developed, and a hybrid integrated solar combined cycle (ISCC) is constructed for comparison purposes. In general, the results show that the proposed system can improve the efficiency of the solar utilization of the new solar chimney with 78% more than the conventional ISCC system. The geometrical dimensions of the solar field and chimney of the new system are smaller than the traditional one; therefore, the estimated capital cost ($/m2) will be relatively less.

太阳能海水淡化塔，设计新颖，仅以蒸汽为工质，用于发电和蒸馏水

摘要 当今，可持续能源的利用是必不可少的。本文研究了一种用于发电和水蒸馏的新型太阳能烟囱工厂。发电厂的运行机制基于使用集中太阳能发电技术蒸发海水。所提议系统的新颖之处在于仅使用蒸汽作为工作流体；此外，集热区与太阳能烟囱分开。太阳能场吸收太阳能并将其传输到蒸汽发生器中。当蒸汽通过烟囱时，蒸汽与外部环境交换热量，导致水在烟囱内表面凝结。已经开发了一组方程，并构建了混合集成太阳能联合循环 (ISCC) 以进行比较。一般来说，结果表明，与传统的ISCC系统相比，所提出的系统可以提高新型太阳能烟囱的太阳能利用效率78%。新系统的太阳能场和烟囱的几何尺寸比传统的要小；因此，估计的资本成本（美元/平方米）将相对较低。
