Abstract：The flue gas after wet desulfurization is saturated wet flue gas,which contains a large amount of water vapor and latent heat.The water vapor and low-temperature waste heat directly discharged are important components of water resources and energy consumption of coal-fired power plants.The paper summarizes the waste heat utilization technologies of flue gas after wet desulfurization,describes the process flow of low-grade waste heat utilization technology such as condensation method,membrane separation method,hygroscopic solution method and slurry flash method,points out their advantages and disadvantages and application scope,and summarizes their current research and application status,providing reference for the waste heat utilization of saturated wet flue gas after wet desulfurization.
