Modeling and thermo-economic optimization of heat recovery heat exchangers using a multimodal genetic algorithm

Energy and exergy analyses of natural gas-fired boilers in a district heating system

“…During a reversible process, when a system comes to the balance with chemical composition, pressure and temeperature of reference environment, the maximum work can be produced. What defined as the exergy it is this [7].…”

Thermodynamic performance simulation and concise formulas for triple-pressure reheat HRSG of gas–steam combined cycle under off-design condition

“…Thermodynamic and thermo-economic approaches have been applied to design the initial parameters [6]. To obtain the optimum values of design parameters, a thermo-economic modelling and optimization method has been adopted for dual-pressure HRSG [7]. A comprehensive exergetic, economic http and environmental analysis has also been performed for combined cycle using different fuels [8].…”

Experimental and numerical investigation of optimum design of semi industrial heat recovery steam generator inlet duct

“…In another study Ameri and Ahmadi [9] studied the effect of ambient temperature on exergy losses of a heat recovery steam generator and concluded that ambient temperature will affect the HRSG performance. Ghazi et al [10] performed a comprehensive thermodynamic modeling of a dual pressure combined cycle power plant and carried out an optimization study to find the best design parameters. Sindareh et al [11] studied the thermodynamic modeling based optimization for thermal systems in heat recovery steam generator during cold start-up operation.…”
