Abstract
An air pollution control apparatus according to the present invention reduces nitrogen oxides and oxidizes mercury in flue gasdischarged from a boiler by an ammonia denitrating catalyst. The air pollution control apparatus includes an economizer bypassing unitthat diverts high-temperature combustion gasto a downstream side while bypassing an economizerprovided in a gas fluefor combustion gasfrom the boiler, provided with an ammonium-chloride supply unitthat supplies powdery ammonium chloride (NHCl) to the economizer bypassing unit. The air pollution control apparatus sublimates the ammonium chloride in an atmosphere at a high temperature of the combustion gas, and supplies hydrogen chloride and ammonium into the flue gas flue
