The purpose of this research is to investigate the feasibility of utilizing low enthalpy geothermal energy in a thermal power system. The Kalina cycle is suggested in this research and will be evaluated in the light of energy and exergy analysis. Binary NH3/H2O mixture will be utilized as a working fluid. Through a parametric study, NH3/H2O mixture strength and geothermal source temperature will be varied and tested against the performance of Kalina system. A comparison with conventional Rankine cycle performance, working at the same boundary conditions, will be also performed.
