“…It is officially reported that these heaters burn 32980 m 3 NG in a year. In order for making an initial economic analysis, key economic criteria such as net present value, internal rate of return, dynamic payback period, and profitability index [50][51][52] are taken into account. These economic indicators are obtained based on a five-year service life assumption.…”

“…The soaring trend in universal energy consumption, as indicated by the World Energy Council, forecasts a significant surge of over 100% in consumed energy over 40 years [1,2]. Fossil fuels dominate global energy production [3]. Despite improvements in harnessing qualified energies, non-renewable sources will play a pivotal role in meeting humanity's energy needs.…”

“…The power plant has a nominal electricity output of 450 MW. They presented two distinct scenarios, including the high-pressure line (HP) and low-pressure line (LP) of the heat recovery steam generator (HRSG) for water production, where the former produces about 25,000 m 3 , while the latter leads to 7000 m 3 . Considering their economic analysis, the price of the produced fresh water is from 2.5 USD/m 3 to 3 USD/m 3 .…”

This paper presents an in-depth investigation into the performance of Mashhad Tous power plant in Iran, a natural-gas-fueled steam cycle with an output power of 4 × 150 MW. The analyses include energy, exergy, and exergoeconomic. To facilitate the study, a robust code is developed to simulate the thermodynamic topology of the power plant. The fidelity of the simulation is validated using realistic site conditions. The study incorporates three vital decision variables: boiler water mass flow rate, turbine inlet pressure from, and ambient temperature ranging from 90 kg⋅s−1 to 150 kg⋅s−1, 12 MPa to 19 MPa, and 10 °C to 40 °C, respectively. Three different heat loads, including 423 MW, 311 MW, and 214 MW, are used to analyze the performance of the power plant. A Pareto-based multi-criteria optimization intertwined with the technique for order of preference by similarity to the ideal solution (TOPSIS) is used to find the optimum conditions in terms of having the highest work output and exergy efficiency while simultaneously reducing the plant’s total cost. The optimization results demonstrate a 4.28% increase in output at full load (423 MW). Additionally, a 1.52% increase is observed at partial load (311 MW), and there is a notable 16% increase in output at low load (214 MW). These improvements also positively impacted energy efficiency. Specifically, there is a 4% improvement at full load, a 0.9% enhancement at partial load, and a remarkable 5.4% increase in energy efficiency at low load. In terms of costs, substantial reductions of 37% at full load, 31% at partial load, and an impressive 72% at low load are evident.

“…Many researchers studied exergy analyses of boilers as used in various industrial settings. In one of the studies, Ebrahimi-Moghadam et al [11] proposed a novel control system for indirect boilers of natural gas pressure reduction stations (PRSs). Their analyses revealed that their proposed system leads up to a 28.54% increment in the boiler sufficiency and USD $3671 of cost saving.…”

A numerical simulation for analysis and optimization of the performance and NOx production was applied to a natural gas fuel boiler in South Pars Gas Complex. For this purpose, nine actual environmental and operational parameters of a boiler were measured and recorded every two hours and then averaged daily for a year. Using the thermodynamic laws, important parameters such as body and exhaust flue gas losses, as well as the thermal efficiency and exergy efficiencies of the combustor and boiler, were calculated for each day. The results show that, owing to changes in the environmental and operational conditions, the thermal and exergy efficiency of the boiler varied from 83% to 87% and 27% to 32%, respectively, during the year. In addition, by optimizing the excess air percentage, the thermal and exergy efficiencies could be increased by 1.5% and 3%, respectively, for most days of the year.
