    摘要： A mercury reduction system includes an NH4Cl supplying unit that sprays an NH4Cl solution into a flue of the boiler, a reduction denitration apparatus that includes a denitration catalyst for reducing NOx in the flue gas with NH3 and oxidizing Hg in the presence of HCl, and a wet desulfurization apparatus for reducing Hg oxidized in the reduction denitration apparatus with limestone-gypsum slurry. The NH4Cl supplying unit includes an NH4Cl solution feed pipe that supplies the NH4Cl solution into the flue in a liquid state, a blow pipe that is inserted into the flue so as to surround the NH4Cl solution feed pipe and through which air is injected into the flue, and a two-fluid nozzle that is fitted to an end of the NH4Cl solution feed pipe and through which the NH4Cl solution is injected. Through the two-fluid nozzle, the NH4Cl solution is injected and sprayed in fine liquid droplets. NH3 is supplied by an ammonia supplying unit and HCl is supplied by a hydrogen chloride supplying unit wherein both units are located between the NH4Cl agent supplying unit and the reduction denitration apparatus.

    摘要： The present invention provides a wet gas purification method in which ammonia in the gas is removed, and a system for carrying out said method, characterized in that the method includes a washing step in which ammonia in the gas is absorbed in an absorbent for removal; and an ammonia treating step in which ammonia is stripped from the discharged absorbent at a following stage of the washing step, wherein the absorbent is divided into an off-gas containing ammonia and effluent. In the washing step makeup water is charged continuously or intermittently so that the concentration of ammonia in the gas having passed through the washing step is 10 ppm or lower. According to the present invention, a wet gas purification method can be performed in which the running costs involved in operation is reduced, the manipulation step and system are simple, operation is easy, and the reliability is high.
