“…They draw conclusion, working fluid with lower critical temperature, such as Isobutane and R227ea and Isobutane are more preferable for ORC power generation. Similar research was studied by (Safa et al) [10], they conducted a study of thermal and exergetic of the Integrated Multi Effect Desalination (MED) and Solar Rankine Cycle (SRC) in Iranian Southern Coastal Region and the result show total exergy destruction is the highest for steam generator and cavity receiver which is in the range of 61% to 64% in several cases. In this paper, evaluation of thermodynamic performance from the exhaust heat of the Tura geothermal power plant will be performed using ORC application in term of energy, exergy, and exergy sustainability aspect.…”

A developing geothermal utilization is one of many Hungarian government efforts to generate electricity and heating applications from renewable energy sector, and to reduce fossil fuels usage due to the impact on the environment. Geothermal utilization for electricity generation has been implemented in Tura region and it is become the first geothermal plant in Hungary that producing electricity around 27 MW. The excess steam from Tura geothermal power-plant still has a potential energy that can converted to electricity and the objection in this study is implemented a heat recovery from excess steam through organic Rankine cycle (ORC) from the point of view energy and exergy analysis using different working fluids. The calculation result shows the Propane is produce the highest energy around 41 kW and the efficiency at 10.3%, while R125 produce the lowest energy around 10.25 kW and the efficiency at 8.17%. Moreover, based on the environmental analysis it is also found that R134a working fluid can be considered as environmentally and sustainability ORC's working fluid, compared to other working fluids, in this study.

“…The exhaust gas, whose temperature drops after this process, is a candidate for a unique, medium-temperature, and sustainable heat source for the ORC. The evaluation of the exhaust gas released due to the combustion of sewage sludge in the FBSSIs for electricity generation with the ORC was discussed partly in only a few published papers in the open literature [33][34][35]. On the other hand, waste heat obtained from WWTP or MSWP integrated into an ORC was extensively studied [36][37][38][39][40].…”

This paper presents the design, evaluation, and optimization of an electricity generation system based on the two-stage organic Rankine cycle (TS-ORC), which utilizes the waste heat of an existing fluidized bed sewage sludge incineration (FBSSI) facility. The facility incinerates an average of 300 tons per day of sewage sludge with a dry matter content of 22%. After the drying process, the sewage sludge is burned in a fluidized bed combustor, and exhaust gas at a temperature of about 850-900ºC is released due to the combustion. The system provides the energy required to dry the sludge from this exhaust gas. In this study, a TS-ORC is designed to be coupled to the exhaust gas flowlines discharged to the atmosphere at two different points in the FBSSI plant. The exergy efficiency of the FBSSI facility is found to be 70.5%. Three different working fluids are selected to examine the variations of thermodynamic and thermoeconomic performance parameters of the designed TS-ORC system. The highest power generation in the TS-ORC system (183.40 kW) is achieved using R1234yf as working fluid. R1234yf is also the most expensive fluid for electricity generation among the other working fluids (10.57 $/h). The least electricity generation in the TS-ORC (142.70 kW) occurs at the thermoeconomically most affordable cost with R245fa (9.35 $/h).
