“…Many researchers, such as Kotas [5], Facchini et al [6], Moran et al [7], Rahim [8,9], Ersayin and Ozgener [10], Ameri et al [11], Deng-Chern and Chuang [12] and Petrakopoulou et al [13] have carried out exergy analyses on combined cycles power plants. Although numerous studies are available in the literature for CCPP, nevertheless none have explored a triple pressure reheat HRSG using a real set of data based on exergy analysis.…”

Energetic and exergetic analyses are conducted using operating data for Sabiya, a combined cycle power plant (CCPP) with an advanced triple pressure reheat heat recovery steam generator (HRSG). Furthermore, a sensitivity analysis is carried out on the HRSG using a recent approach to differentiate between the sources of irreversibility. The proposed system was modelled using the IPSEpro software and further validated by the manufacturer's data. The performance of the Sabiya CCPP was examined for different climatic conditions, pressure ratios, pinch point temperatures, high-pressure steam, and condenser pressure values. The results confirmed that 60.9% of the total exergy destruction occurs in the combustion chamber, which constitutes the main source of irreversibilities within a system. The exergy destruction was significantly affected by both the pressure ratio and the high-pressure steam, where the relation between them was seen to be inversely proportional. The high-pressure stage contributes about 50% of the exergy destruction within the HRSG compared to other stages and the reheat system, due to the high temperature difference between the streams and the large number of components, which leads to high energy loss to the surroundings. Numerous possibilities for improving the CCPP's performance are introduced, based on the obtained results.

“…For a particular pressure ratio, thermal efficiency increases either with the increase in turbine inlet temperature or with the decrease in heat exchanger cold end temperature. Sue and Chuang [36] presented in his paper the engineering design and theoretical exergetic analyses of the plant for combustion. The results show the exergy analyses for a steam cycle system predict the plant efficiency more precisely.…”

“…Moreover, decrement of the helium temperature at the compressor inlet caused sharp drop in the compression work due to the decrement of the specific volume. There are several studies regarding to the working fluids which are used in ORC in literature [5][6][7][8][9][10][11][12][13][14][15]. As understood from these studies, the working fluid used in the ORC cycle has important effect on the performance of the power generation systems.…”

In this study, energy and exergy analyses are performed for an Organic Rankine Cycle in a local power plant that is located southern of Turkey. The Organic Rankine Cycle was used for low temperature heat source as heat recovery process with various organic working fluids. The examined system consists of an evaporator, a turbine, a condenser, a pump and a generator as components. The evaluation is carried out using two different working fluids for each component of the system. The main purpose of this study is to model the ORC cycle for performance optimization in terms of the usage of two different working fluids with relevant temperature ranges. HFE7100 and FC72 working fluids are selected as performance parameters in order to show the effect of the working fluids on the system performance of the Organic Rankine Cycle.
