摘要

近年来，燃气轮机循环（GTC）的混合能源集成引起了人们的关注，因为它提高了效率，减少了依赖单一能源的缺点，如间歇性或高排放。在这项研究中，提出了一种采用太阳能发电塔（SPT）和沼气燃料燃烧室的混合配置来驱动GTC。该系统通过有机朗肯循环（ORC）、热回收蒸汽发生器和改进的Kalina循环（MKC）的组合利用GTC的余热。此外，ORC和MKC的余热通过热电发电机和吸收式制冷机进一步回收，以提高整体能源利用率。ORC和MKC产生的电力被引导到质子交换膜电解槽和反渗透海水淡化装置，用于联合生产氢气和淡水，有效地将系统转变为一种新的多产布局。建立了一个综合的数学模型，从能源、能源、能源经济和环境的角度来评估该系统。分析了关键参数对系统性能的影响，并以最大的火用效率和最小的总成本率为目标进行了多目标优化。在基本方案中，SPT是系统中的主要组成部分，占总火用破坏的68.33%，占总初始成本的75.62%，占与火用破坏相关的成本的68.93%。优化结果产生的火用效率为30.491%，总成本率为5832.14美元/小时，与基本情况的输出相比，分别提高了4.3%和1.8%。在最佳条件下，该系统可提供20,632 kW的电力，33,201 kW的供暖，3,003 kW的制冷，以及6.399 kg/h的氢气和16.07 kg/s的淡水。与现有设计相比，提出的混合spt -沼气GTC配置显示出更高的效率和成本效益，证实了其集成生产电力、热量、冷却、氢气和淡化水的潜力。

Integrated 4E evaluation and optimization of a hybrid solar–biogas gas turbine system for sustainable hydrogen and desalinated water production

Hybrid energy integration into gas turbine cycles (GTC) has gained attention in recent years, as it improves efficiency and reduces the drawbacks of relying on a single energy source, such as intermittency or high emissions. In this study, a hybrid configuration employing a solar power tower (SPT) and a biogas-fueled combustion chamber is proposed to drive a GTC. The system utilizes the waste heat from the GTC through a combination of an organic Rankine cycle (ORC), a heat recovery steam generator, and a modified Kalina cycle (MKC). Additionally, residual heat from the ORC and MKC is further recovered by a thermoelectric generator and an absorption chiller to enhance overall energy utilization. The electricity generated by the ORC and MKC is directed to a proton exchange membrane electrolyzer and a reverse osmosis desalination unit for the co-production of hydrogen and freshwater, effectively transforming the system into a novel poly-generation layout. A comprehensive mathematical model is developed to evaluate the system from energy, exergy, exergoeconomic, and environmental perspectives. The influence of key parameters on system performance is analyzed, followed by a multi-objective optimization targeting maximum exergy efficiency and minimum total cost rate. In the base scenario, the SPT represents the dominant component in the system, contributing 68.33 % to overall exergy destruction, 75.62 % to the total initial cost, and 68.93 % to the cost associated with exergy destruction. Optimization results yield an exergy efficiency of 30.491 % and a total cost rate of 5832.14 $/h, showing improvements of 4.3 % and 1.8 %, respectively, compared to base case outputs. Under optimal conditions, the system delivers 20,632 kW of electricity, 33,201 kW of heating, 3,003 kW of cooling, along with 6.399 kg/h of hydrogen and 16.07 kg/s of freshwater. Compared to existing designs, the proposed hybrid SPT–biogas GTC configuration demonstrates enhanced efficiency and cost-effectiveness, confirming its potential for integrated production of power, heat, cooling, hydrogen, and desalinated water.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
