Thermodynamic Analysis of a Combined Gas Turbine ORC Using Some Organic Fluids

Abstract

The increase in energy and environmental problems from day to day has led us to use sustainable methods of optimizing energy systems. In this study, mass flow rates, pressure ratios, net powers and thermodynamic calculations were performed by adding the integrated organic rankine cycle (ORC) to the waste heat of a gas turbine (GT) on behalf of innovative concepts in industrial competition and operating five different fluids (R123, R245fa, R600a, R236ea and R134a) with a specific heat in this ORC system. The gas turbine integrated with the R123 refrigerant was found to provide the best net power. The mass, energy, and exergy destructions for each component are summarized in tables separately. The energy efficiency of the designed integrated cystream was calculated as 66%, and the exergy efficiency was calculated as 20%. It is seen that the importance of sustainable energy in the optimization of power systems combined with ORC is inevitable.
