“…The fuel of this plant was natural gas, Suggestions for integrated chemical absorption process were represented by applying exergy analysis in order to work more efficiently. Kumari perform a research on the basic‐gas‐turbine and intercooled‐gas‐turbine cycles and analyzed the influence of several cycle working factors on the performance of the mentioned cycles. The obtained results for rational efficiency and component‐wise destruction of exergy for the investigated cycles are shown in Figure .…”

Surging in energy demand makes it necessary to improve performance of plant equipment and optimize operation of thermal power plants. Inasmuch as thermal power plants depend on fossil fuels, their optimization can be challenging due to the environmental issues which must be considered. Nowadays, the vast majority of power plants are designed based on energetic performance obtained from first law of thermodynamic. In some cases, energy balance of a system is not appropriate tool to diagnose malfunctions of the system. Exergy analysis is a powerful method for determining the losses existing in a system. Since exergy analysis can evaluate quality of the energy, it enables designers to make intricate thermodynamic systems operates more efficiently. These days, power plant optimization based on economic criteria is a critical problem because of their complex structure. In this study, a comprehensive analysis including energy, exergy, economic (3‐E) analyses, and their applications related to various thermal power plants are reviewed and scrutinized.

“…In addition, they determined that the gas turbine cycle element with the highest exergy-economic factor is the high-pressure turbine. The effect of different gas turbine cycle operating parameters such as on the energy performance of two different gas turbine cycles including "basic gas turbine cycle" and "intercooled gas turbine cycle" was investigated by (Kumari and Sanjay, 2015). It was resulted that the total exergy destruction of "intercooled gas turbine cycle" was less than that of basic gas turbine cycle by 4.42%.…”

N owadays, the importance of electricity generating systems by means of renewable energy such as wind and sun has been increasing because of decreasing the life of fossil fuels, but a large part of the need for electricity from fossil-based fuels is provided by power plants. In power generating plants, the emissions of power plants are considered as important parameters that must be taken into consideration. Interest in gas-fired gas turbine power plants has been increasing day by day because of low investment cost, efficient operation and minimal environmental impacts. It is not enough to analyse the thermal systems only in terms of the conservation of energy. Because the conservation of energy analyses systems only quantitatively in terms of energy balance. However, the second law of thermodynamics performs

“…(3) The negative effects of intercooling have been reported in previous studies [11,18,[20][21][22][23], but the power consumption of pumps to drive intercoolers has received limited attention. One way to reflect the drawback of the intercooling better is regarding the pumps as customers of the output power offered by the intercooled gas turbine.…”

The intercooled gas turbine obtained by adopting an indirect heat exchanger into an existing gas turbine is one of the candidates for developing high-power marine power units. To simplify such a strong coupled nonlinear system reasonably, the feasibility and availability of qualifying equivalent effectiveness as the only parameter to evaluate the intercooler behavior are investigated. Regarding equivalent effectiveness as an additional degree of freedom, the steady state model of a marine intercooled gas turbine is developed and its off-design performance is analyzed. With comprehensive considerations given to various phase missions of ships, operational flexibility, mechanical constraints, and thermal constraints, the operating curve of the intercooled gas turbine is optimized based on graphical method in three-dimensional performance space. The resulting operating curve revealed that the control strategy at the steady state conditions for the intercooled gas turbine should be variable cycle control. The necessity of integration optimization design for gas turbine and intercooler is indicated and the modeling and analysis method developed in this paper should be beneficial to it.
