description: This study aims to select the most suitable working fluid for the ORC under the conditions provided. In ORC, turbine, condenser, evaporator and pump efficiencies are determined as 85%, 99% 99% 98%, respectively. In the first calculation, for R600a, R114, R245fa, R123, R1234ze(E) fluids, the temperature 10 degrees below the critical temperature and the pressure accordingly were determined and accepted as turbine input values. Calculations in the second and third conditions were made by choosing the lowest possible value and average value for pressure and temperature, providing the superheated steam condition. Net power output is capped at 1 MW. As a result of these conditions, mass flow and efficiency values were obtained for each fluid. The most suitable fluid to be used was chosen as R245fa, which was applied at the turbine inlet at 417 K, 3 MPa values, resulting in a mass flow rate of 18.22 kg/s and an efficiency of 20.68%. ORC which using R245fa fluid was applied in addition to the combined power plant including the Brayton Cycle and the classical Rankine cycle, and it was calculated that the total thermal efficiency increased from 52.8% to 54.4%.
