摘要
an HCI atomizer (32) that sprays hydrogen chloride (33) to flue gas from a coal combustion boiler (11) that uses coal as a fuel (F); NOx removing apparatus (13) that removes nitrogen oxides by ammonia denitration by adding ammonia (12) to the flue gas after spraying hydrogen chloride and oxidizes mercury; an air preheater (14) that recovers heat in the gas after removal of nitrogen oxides; a precipitator (15) that removes particulates in the gas; an activated carbon atomizer (22) that sprays activated carbon (22a) into the gas after particulate collection; a bag filter (21) that collects activated carbon having adsorbed mercury; a desulfurizer (16) that removes sulfur oxides in the flue gas after removal of activated carbon; a stack (17) that discharges the gas which has undergone desulfurization to outside; and an ORP meter (19) that measures an oxidation reduction potential for feeding air to a slurry absorbent in the desulfurizer (16).
