Abstract

PURPOSE:To prevent the corrosion or the like of a water sealing apparatus member, by adjusting the pH and the solid content of water used in sealing water provided in exhaust gas line. CONSTITUTION:A part of recirculated water is withdrawn from the emitting side of a recirculation pump 11 in order to adjust the pH and the solid content of said recirculated water and the withdrawn liquid is supplied to a solid-liquid separator 14 to separate and remove solid components such as fly ash, an adsorbent powder or the like while the solid components after separation are discharged out of the system and the liquid is sent to a pH adjusting tank 15. The liquid in the pH adjusting tank 15 is neutralized by an alkali solution corresponding to the acidic gas dissolved in sealing water from exchaust gas D to return the pH to neutral and, herein, moisture and steam discharged out of system along with the solid components separated by the solid-liquid separator 14 are replenished. Because the sealing water made neutral in the pH adjusting tank 15 can be repeatedly used, it is returned to a sealing water holding tank 10.
