“…The sum of the thermomechanical exergy and chemical exergy is called the total exergy [22]. Exergy analysis is usually applied for an existing process to find out the location or locations to which improvements need to make such that the overall energy efficiency of the process can be enhanced effectively [23]. In this paper, exergy analysis is performed according to the chemical reactions of the five routes of hydrogen production from various sulfur-containing feedstock.…”

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.

“…The primary objectives of this study were to analyze the system components separately and to identify and quantify the sites having largest exergy and energy losses. Reddy et al (2010) carried out a thermodynamic analysis of a coalbased thermal power plant and gas-based cogeneration power plant. The paper analyzed the information available in the open literature regarding exergy and energy analysis on high-temperature power plant.…”

This paper presents the thermodynamic modeling and validation of a 210-MW subcritical coal-fired power plant situated in North India. In the era of high computing facilities available, modeling and simulation have become a very pertinent tool for design and development. As such, the objective of the present work is not to enhance the thermal conversion efficiency, but to represent the thermal system in a simplistic yet functional manner. The thermal performance module consists of the following main sections such as steam boiler, economizer, superheater, reheater, steam turbine, condensate extraction pump, boiler feed pump, feedwater heaters and condenser. Thus, a semi-empirical module has been developed to predict thermal performance of coal-fired power plant. It includes the mass balance, energy balance, thermodynamic property relations for working substance followed by empirical correlations for steam bled pressure and thermodynamics of a steam power cycle. By using the MATLAB calculation tool, a process-based computer program of the coal-fired power plant has been successfully validated for thermal efficiency, steam flow rate and coal consumption rate at wide plant load range. The predictions were compared with operating data of 210-MW thermal power plant at different power output levels. The predicted results agree with plant operating data.
