International Journal of Global Warming (IJGW), Vol. 26, No. 1, 2022

Abstract: This study aims to perform energy, exergy, economic and emission-removal performance analysis of wet flue gas desulphurisation (FGD) systems in a coal-fired power plant with 660-MW capacity. The outcomes of the analysis reveal that energy and exergy performances are negatively correlated with flue gas temperature enhancement. The energy and exergy efficiency improved by 10% in the case of integration of the heat recovery unit into the system. Furthermore, the increase in the pH value of the FGD plant and the increase in the number of running pumps positively affect the emission removal efficiency; on the other hand, the increase of the power plant load had an adverse effect. According to economic analysis, the obtained results show that the profit generated by the gypsum trade can be accepted economically, and the NPV of the system could be increased to $880,698 because of the integration of the heat recovery unit into the system.
