N2 - In recent years, there has been a growing interest in the ultrafine particle (PM2.5), because public health has been threatened. Gas-phase sulfur oxides discharged from the coal-fired power plants are designated as the main source of ultrafine dust. Therefore, coal-fired power plants are operating flue gas desulfurization facilities to remove gas-phase sulfur oxides from the exhaust gas. In this study, computational fluid dynamics (CFD) simulations for Yeosu thermal power plant Unit 1 desulfurization system were performed. Specifically, the effect of guide vane shape on duct flow characteristics was studied. The operating conditions were 115% BMCR, and the flow velocity distribution and velocity uniformity of the exhaust gas were compared for the initially designed, and the three additional guide vane shapes. Considering minimum fluid collision and maximum velocity uniformity, the optimal design case of the guide vane was suggested.
