Özet:

 


Turkey's
energy consumption has risen in conjunction with its economic growth over the
past decades. However, approximately 70 % of the electricity demand is supplied
by fossil-based fuels, which are mainly imported from other countries. Thus, it
became very important for the country to find alternative ways of meeting the
energy requirement. Due to its geographical position, the renewable energy
potential of Turkey is fairly well, which is currently contributing to the
energy generation but not at the desired level. One of them is the geothermal
energy that Turkey has many geothermal areas, and they are relatively
appropriate for electricity production. This study aims to investigate the
performance of a geothermal based transcritical Rankine cycle for various
supercritical working fluids. The geothermal reservoir is located in the west
part of Turkey, and the geothermal water temperature is about 156 °C. Using the
actual data, comparative thermodynamic analyses are carried out for determining
the best working fluid. Results show that the highest power generation rate is
calculated for the cycle using R170 with 6125 kW, followed by R744. In
addition, the highest irreversibility is calculated for R125 with an exergy
destruction rate of 8397 kW.
