<p><P>PROBLEM TO BE SOLVED: To provide an exhaust gas treating method and an exhaust gas treatment apparatus, which remove harmful substance and prevent failure like corrosion of a flue, even if excessive HCL for removing mercury is contained in exhaust gas, regardless of the kind of coal or the property of exhaust gas discharged from a combustion apparatus, when burning coal in the combustion apparatus like a boiler. <P>SOLUTION: This invention relates to the exhaust gas treating method for removing mercury contained in exhaust gas discharged from a coal-burning boiler B, when burning fossil fuel like coal C in the coal-burning boiler B. Crushed coal C and a chlorine compound Cl are fed to the coal-burning boiler B for combustion, a hydrogen chloride adsorbent is fed to the vicinity of the upstream side of a dust removing part 5 disposed in a flue R from the coal-burning boiler B for adsorbing excessive hydrogen chloride, and the hydrogen chloride adsorbent having adsorbed hydrogen chloride is collected in the dust removing part 5 together with soot. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
