Comparative Analysis of Kalina Cycle Configurations Coupled with Dual-Ejector Organic Flash Cycles for Geothermal Power Enhancement |
|
| چکیده انگلیسی مقاله |
The growing need for sustainable energy solutions has driven advancements in waste heat recovery and renewable energy technologies. This research explores the efficiency of two hybrid configurations that merge Kalina cycles (KCS-11 and KCS-34) with a dual-ejector organic flash cycle, utilizing geothermal energy as the primary heat source. A thorough thermodynamic study is conducted, focusing on system performance, the effect of important factors like geothermal input temperature, ammonia mass fraction, and turbine inlet pressure. The KCS-34-DE-OFC system demonstrated superior performance compared to the KCS-11-DE-OFC system, achieving a peak net power output of 584.8 kW along with maximum thermal and exergy efficiencies of 16.55% and 57.56%, respectively. This study demonstrates the significant potential of dual-ejector integration and advanced cycle configurations for efficient geothermal energy utilization, offering a sustainable approach to meeting global energy demands. |
