PROBLEM TO BE SOLVED: To provide an exhaust gas treating facility capable of improving a heat recovering efficiency with an easy operation without necessity of incorporating an allowance in the facility. SOLUTION: The exhaust gas treating facility comprises a re-combustor 12 for partly burning an exhaust gas G at a high temperature by applying an air or an oxygen or their mixture gas to the gas G, a front stage boiler 13 for introducing outlet gas from the re-combustor 12 to recover a waste heat incorporated in the exhaust gas, a gas cleaning unit for dry dust-removing the outlet gas from the boiler 13 and removing an acid component such as a hydrochloric acid, a sulfide or the like contained in the gas, a re-combustor 22 for completely burning by applying the air or the oxygen or their mixture gas to the cleaned gas and re-burning the gas at a high temperature, and a rear stage boiler 23 for recovering the waste heat incorporated in the gas by introducing the outlet gas from the re-combustor 22. |
