AIR POLLUTION CONTROL APPARATUS AND AIR POLLUTION CONTROL METHOD |
摘要 |
An air pollution control apparatus according to the present invention reduces nitrogen oxides and oxidizes mercury in flue gas 16 discharged from a boiler by an ammonia denitrating catalyst. The air pollution control apparatus includes an economizer bypassing unit 15a that diverts high-temperature combustion gas 11 to a downstream side while bypassing an economizer 15 provided in a gas flue 10a for combustion gas 11 from the boiler, provided with an ammonium-chloride supply unit 101 that supplies powdery ammonium chloride (NH4Cl) to the economizer bypassing unit 15a. The air pollution control apparatus sublimates the ammonium chloride in an atmosphere at a high temperature of the combustion gas 11, and supplies hydrogen chloride and ammonium into the flue gas flue 102.
