“…Important aspects to be accounted for are the geothermal resources characteristics Franco and Vaccaro (2012), the design of the conversion cycle, which has to be optimized to maximize its efficiency Franco and Vaccaro (2012); Franco and Villani (2009); Hettiarachchi et al (2007), the choice of the working fluid for binary cycles Saleh et al (2007); Heberle and Brüggemann (2010); Guo et al (2011a,b), and the district heating parameters for CHP applications Guo et al (2011a,b). The thermodynamic performance is as well critical to ensure an efficient use of the resource, and it can be assessed using the exergy efficiency DiPippo (2004); Kanoglu and Dincer (2009);Coskun et al (2011);Ganjehsarabi et al (2011).…”

“…Kanoglu and Bolatturk [11] studied exergy analysis of a binary geothermal power plant using actual plant data to assess the plant performance and pinpoint sites of primary exergy destruction. Exergy destruction throughout the plant was quantified and illustrated using an exergy diagram and compared to the energy diagram.…”

Electricity generation is achieved by means of the medium-temperature geothermal water in the range of 90-140 ºC in binary plants with the organic Rankine cycle. So, we investigate a binary geothermal power plant as a case study, from the energy and exergy point of view. Also, exergy destruction rates throughout the plant are quantified and illustrated for comparison purposes. In the plant considered, the brine injection and reinjection temperatures are 140 and 80 ºC, with a mass flow rate of 64.87 kg/s, respectively. The energy and exergy efficiencies are calculated as 5.34 and 30.84 %, respectively, based on the heat and exergy input rates to the system at the net power. Furthermore, we examine the effects of some parameters on energy and exergy efficiencies and net power output (e.g., brine injection temperature, brine mass flow rates, turbine inlet temperature and inlet pressure).

“…Recently Ganjehsarabi, Gungor and Dincer [61] presented an exergy analysis of the Dora II (9.5 MW net power) geothermal power plant, located in Aydin, Turkey. In the case of Olkaria I Power Plant in Kenya, Kwambai [62] calculated the overall second law efficiency of a plant and presented the diagram of exergy flow through the system.…”

a b s t r a c tDuring the last decade, a design of an energy efficient and cost effective geothermal plant represents a significant and on-going technical challenge in all the Western Balkan countries. In the Republic of Croatia, the geothermal field Velika Ciglena is identified as one of the most valuable geothermal heat sources and probably the location where the first geothermal plant in the Western Balkan area will be built. The purpose of this work is the conceptual design and performance analysis of the binary plants ethe one which operates under the Organic Rankine Cycle (ORC) and the other under Kalina (KLN) cycleewhich can be used for geothermal energy utilization in Velika Ciglena. A conceptual plant design is performed by the equation-oriented modelling approach and supported by the two steady-state spreadsheet simulators. The performance analysis of all design solutions is conducted through energy and exergy analysis, and by the estimated total cost of operating units in the plant. The results of the analysis indicate that the plant design based on the ORC cycle has a higher thermodynamic efficiency and lower cost of equipment, and consequently, it is more suitable for the future geothermal plant in Velika Ciglena.
