“…The evaporation rate is 3.8%, which is close to, though not the same as, the numerical and experimental data of Hosseini Araghi, Khiadani 27 and Hosseini Araghi, Khiadani 28 . It is important to notice that the evaporation rate obtained in the present power block is lower than the obtained by Araghi, Khiadani 29 in his Rankine power cycle based on natural gas. This is mainly because those authors designed the power cycle specifically to produce water, which decreases the cycle thermal conversion efficiency.…”

“…The evaporation rate or water recovery is similar to the three cases of study, although this value is slightly lower than the one obtained in similar works using organic Rankine power cycle. 28,29 Here, we analyze the viability of incorporating a desalination process that uses the waste heat without sacrificing the power cycle efficiency as otherwise this would have led to a considerable increase in the CST equipment cost.…”

“…Moser, Trieb 16 and Leiva‐Illanes, Escobar 20 analyzed the integration of a MED into a CST system based on a Rankine Cycle. Araghi, Khiadani 29 evaluated the feasibility of incorporating a low thermal desalination system into a 5 MW power plant. Ortega‐Delgado, García‐Rodríguez 30 studied the incorporation of RO or MED into a 5 MW CST system.…”

This paper proposes the use of a hybrid 5 MW power generation system combining concentrated solar thermal and solar photovoltaic technology where the efficiency of the power block is increased by taking advantage of hot water from a low-temperature geothermal source. Aiming at a case study for Winton in Queensland the pertinent meteorological data are used for our simulations.In addition, the paper analyzes the feasibility of including a thermal desalination technology that uses the waste heat from the power block for producing clean water from wastewater. Our design replaces the traditional dry cooling system with a water-cooled heat exchanger to remove the waste heat from the power block. Finally, this work explores the ratio of concentrated solar thermal and photovoltaic electricity production that optimizes the levelized cost of electricity and water production. the results indicate that the incorporation of the desalination system does not produce a significant increase in this value, and the optimal ratio of electricity production is obtained when the photovoltaic system contributes to 27.5% of the total electricity generation. Our water production cost can be as low as 40 ₵/m 3 while for the combined system our minimum levelized cost of electricity figures out at 12.4 ₵/kWh to generate the base load with thermal storage.

“…They claimed that the heat and electrical energies raised up to 518.78%, and emission formations abated up to 7.57% with the double Benders decomposition. Araghi et al analyzed the efficiency and power characteristics of a novel combined‐vacuum desalination and power system operating with R290 and R600a as working fluids. It was demonstrated that the developed system provides higher amounts of fresh water compared with conventional desalination systems.…”

Summary In this study, exergy and thermo‐ecology–based performance analyses of a mercury‐steam combined–energy‐generation system are comprehensively presented. Performance characteristics such as net‐power output, net‐power density, exergy efficiency, exergy destruction, and ecological coefficient of performance have been obtained by developing a novel numerical model. The impacts of the pressures of open feed water heater and steam turbines, temperatures of mercury boiler, and mercury turbines on the performance characteristics have been investigated. The results indicated that the performance characteristics of the system have been remarkably affected by the pressure and temperature variations of the system components.

“…Chacartegui et al [63] investigated using low calorific fuels in a combined cycle and re-designed the combined cycle components. Araghi et al [64] used R290 and R600a as working fluids to examine the performance characteristics of a novel combined power generation and desalination system, and it was demonstrated that the recommended system generates more freshwater in comparison with the classical system. Yao et al [65] suggested and analyzed the performance properties of a new combined system which provides power, cooling and heating requirements.…”

This paper reports a comprehensive investigation of performances for a gas-steam combined power system (GSCPS) by considering exergy and thermo-ecology criteria. The most known and important parameters such as power density, power output, exergy destruction, exergetic efficiency, ecological coefficient performance (ECOP) and effective ecological power density (EFECPOD) are investigated. The influences of turbine design parameters such as turbine speed, mass flow rate of the working fluid, pressure ratio, equivalence ratio, intake air temperatures and pressures, residual gas fraction, fluid temperatures in heat exchanger, the pressure of high-pressure steam turbine, the pressure of medium-pressure steam turbine, the pressure of low-pressure steam turbine, the pressure of open feedwater heater, the pressure of condenser on the performance specifications have been evaluated. The results indicated that the component properties have remarkable impacts on the performance parameters of the GSCPS.
