| Abstract: | According to the typical process and the design parameters of a limestone/gypsum wet flue gas desulfurization system and the gas flow condition in sprayer, the dust removal mechanism and the main influencing factors, including inertial impact, trapping and Brownian diffusion in the sprayer, are analyzed. A mathematical dust-removing model for counter-current spray tower is established, and it is applied in the project to verify the technologies against the emission standard in power plants burned with Zhungeer coal. |
