<p>PURPOSE:To save water supply to an absorption device by reducing moisture drained into an area outside a system as an entrained one in treated discharged smoke. CONSTITUTION:At least, part of an absorbent based on a calcium absorbent is extracted from an absorption system loop 8, and the extracted absorbent is introduced into an indirect cooling-type heat exchanger 9. After cooling the absorbent using a coolant, the absorbent is returned to the absorption system loop to lower the temperature of an absorption liquid slurry supplied to a gas/ liquid contact part. Further, an exhaust smoke is washed by the absorption liquid slurry at a low temperature and the temperature of the exhaust smoke after washing is maintained at the adiabatic cooling saturation temperature level of the exhaust smoke before washing.</p> |
