A review of unconventional bottoming cycles for waste heat recovery: Part I – Analysis, design, and optimization

摘要: Abstract In this paper, an extensive overview of unconventional waste heat recovery power cycles is presented. The three-unconventional bottoming discussed in paper are the air cycle, carbon dioxide-based and Kalina cycle. review divided into two parts; first part about a detailed discussion energy, exergy, economic analysis, as well reviewing load component design, augmentation comparative studies. Whereas, second demonstrate thoroughly applications aforementioned cycles, including renewable energy sources. According to literature, it was found that cycle not competitive when compared conventional such steam Rankine Nevertheless, can be economically for low system capacities. Furthermore, CO2 have shown better performance terms energetic exergetic analyses cycles. transcritical supercritical excel recover medium grade heat, respectively. Finally, low-grade organic addition, optimizing ammonia-water concentrations at different stages has most notable effect improving cycle’s performance.
