摘要

The present study deals with the development and thermodynamic assessments of a solar-assisted Kalina cycle with solar energy as the prime mover. Three configurations of the studied systems were suggested based on using different strategies for waste heat management. A comparative thermodynamic analysis is developed to show the influences of proposed arrangements on the performance of the system. A parametric study is done to find the thermodynamic behavior of the SolKa/TEG-FC system by changing some crucial parameters, such as turbine inlet pressure (TIP), turbine inlet temperature (TIT), and a number of parabolic trough collector (N-CPC), as well as the concentration of inlet stream to the separator. The results indicated that adding the TEG unit to the SolKa system enhances the thermal efficiency by 0.68% and adding the PEM fuel cell with the TEG unit improves the thermal efficiency by 6.8%. The SolKa/TEG and SolKa/TEG-FC arrangements generate 3.27 and 38.95 kW more output power than the Solka system, respectively. Parametric analysis of SolKafTEG-FC system for the TIT from 104 to 120 degrees C leads to increasing output power of about 48.7 kW. The result of the current study can provide a good vision to design a better Kalina cycle integrated with solar energy.
