Semi-dry FGD System

WebFeb 4, 2024 · Semi-dry flue gas desulfurization (FGD) technology is used by some coal-based power plants to remove sulfur dioxide from flue gas. In semi-dry FGD systems, SO 2 is removed by calcium-based sorbents in a reactive spray dryer, but the level of desulfurization is lower than in wet FGD systems. WebMay 27, 2024 · The process of flue gas circulating fluidized bed semi-dry high-efficiency desulfurization system is mainly used for boiler flue gas desulfurization in power stations, iron and steel metallurgy, petrochemical, building materials, etc. The flue gas processing capacity of a single tower can be applied to 6MW to 300MW units. hôpital jossigny irm https://piningwoodstudio.com
