A flue gas control system of a coal combustion boiler comprises an HCl atomizer that sprays hydrogen chloride to flue gas from a coal combustion boiler that uses coal as a fuel; NOx removing apparatus that removes nitrogen oxides by ammonia denitration by adding ammonia to the flue gas after spraying hydrogen chloride and oxidizes mercury; an air preheater that recovers heat in the gas after removal of nitrogen oxides; a precipitator that removes particulates in the gas; an activated carbon atomizer that sprays activated carbon into the gas after particulate collection; a bag filter that collects activated carbon having adsorbed mercury; a desulfurizer that removes sulfur oxides in the flue gas after removal of activated carbon; a stack that discharges the gas which has undergone desulfurization to outside; and an ORP meter that measures an oxidation reduction potential for feeding air to a slurry absorbent in the desulfurizer.
