Study on Mercury Emission Control of Dust Removal System for 300MW Coal-Fired Units

Abstract:

In this study we researched on the gaseous mercury removal performances of fabric filter (FF), electrostatic precipitator (ESP) and wet flue gas desulfurization (FGD) technologies on 300 MW coal-fired boilers, gaseous mercury sampling was conducted according to US EPA Method 30B and Method 29, and the changes of various forms of mercury before and after the dust removal treatment were analyzed. The results show that FF is the most effective for fine particles removal, and more than 99.5 % of the particulate mercury was removed; the gaseous mercury removal efficiency of ESP was only 30%, while the efficiency of FF was 45% or higher; the combination of FF and wet FGD could remove 63.65 % of the gaseous mercury.
