摘要

Researchers are increasingly interested in renewable energy-focused power generation cycles. The literature investigates the power generation systems’ performance parametrically through energy and exergy analysis. The low-temperature Kalina power system, with a cooling water inlet temperature of 35 °C to the condenser, has not yet undergone the exergoenvironmental investigation. The present study looks at the parametric aspects of the zeotropic mixture Kalina cycle system using thermoeconomic, advanced exergy and exergoenvironmental methods that work with 35 °C cooling water. The component turbine and evaporator’s exergetic efficiency have resulted in a maximum of 90% and 85% respectively. The heat exchangers, condenser and superheater have been identified with lower exergetic efficiency values. Hence, improvement in the design aspects of the lower-performance components is needed. The higher the exergetic efficiency, the higher the component’s total cost rate. In both real and ideal conditions, the turbine’s total cost rate is high as a function of the separator vapour fraction. The destruction in the evaporator claims 56 and 32.5 kW for the real and ideal conditions respectively. The conventional environmental impact on the superheater is 94.33%, followed by the economizer and condenser.
