Abstract:
A system for removing Hg contained in flue gas from a boiler, the system includes: a heat exchanger for performing heat exchange of the flue gas from the boiler; a precipitator for removing soot and dust in the flue gas; a wet desulfurization device for removing mercury oxide Hg2+ in the flue gas using an alkali absorbent; and; a removal assistant supply unit for supplying a removal assistant for removing impurities into a limestone and gypsum slurry that circulates through the wet desulfurization device.
