Comparing the efficiency of two different models of combined parallel flash binary cycles

Aria Jafar Yazdi

The main aim of this paper is a comparative study of two different geothermal power plant concepts, based on the exergy analysis. The cycles studied in this paper are the combination of single and double flash power plants with two different ORC cycles as regenerative ORC and regenerative ORC with an IHE, with R113 as working fluid. The main gain due to using combined flash-binary power plants with various types of ORCs is to achieve optimum and efficient energy utilization for Sabalan geothermal power plants.
