Even though coal resources are the most abundant among fossil fuels, coal-fred plants release large amounts of greenhouse gases into the atmosphere. In this regard, reducing environmental challenges and crises caused by coal burning can be a promising option to reduce today s crises in the energy feld. The integration of coal-fred plants with renewable-driven energy systems can simultaneously improve thermodynamic performance and reduce pollutants emission rates. This article presents the thermodynamic and pollutant emission investigations of a new coal-fred plant coupled with a linear Fresnel solar collector (LFSC)-driven solar unit, a parabolic trough solar collector (PTSC)-driven solar unit, a high-Temperature fuel cell stack (molten carbonate fuel cell stack [MCFCS]) and a heat recovery system (based on the steam turbine and gas turbine-based power cycles). The plant is able to produce electricity and hot water (HW). The main structure of the ofered plant is based on coal, whereas, is coupled with renewables-based cycles to mitigate environmental impacts. The plant could generate ∼ 207 MW of power and 3728 m3/h of HW. In such conditions, the energy efciency of 73.1% and exergy efciency of 44.18% could be achievable. Further, the emitted gas rates of the plant were nearly 403 tons/h. A comprehensive comparison is also presented for the plant s behavior under diferent types of coal (petcoke and anthracite). In addition, a two-function optimization is developed to determine the maximum value of exergy efciency and the minimum value of total pollutants emission rate. © The Author(s) 2023.
