Abstract

of fossil fuels, as well as environmental restrictions, the demand for high-efficiency energy systems has risen. For this reason, there is a growing tendency to use combined cycle and cogeneration. In the current research, Brayton and reverse Brayton units have been employed as stimuli in the cogeneration system. In this study, a system for the simultaneous production of power and fresh water, operating on biogas fuel, is presented. The performance of the combined system has been evaluated in terms of the first and second laws of thermodynamics. Additionally, to examine the system's behavior with varying input parameters, a parametric study has been conducted. Also acc ording to the obtaine d results, the presented system has the a bility to produce 1031kW of power and 0.8498 m^3/h of fresh water. The energy and exergy efficiency of this system are calculated as 35.65% and 36.21%, , respectively.
