The generation of electrical power by thermal plants is critically for national security reasons, namely to ensure the sustainability of the grid system. The thermal plant was forced to reduce the emission emitted into the atmosphere, which is emitted through the coal combustion process. Faced with these issues and problems, installation of the FGD system at thermal plants is necessary to improve these conditions. This experimental study was conducted at a 700-megawatt coal fired power plant in order to determine the effectiveness of the FGD system. Findings show that different types of sub-bituminous coal led to varying percentages of SO2, NOx, CO, CO2, and Opacity and about 30% to 50% of the contaminate gasses reduce with FGD in system. Findings also show that the coal Gross Calorific Value (GCV) above 5000 kg/kcal recorded high temperatures at the flue gas outlet and it did not affect the amount of gas released into the atmosphere.
