PROBLEM TO BE SOLVED: To provide a novel gas treating device for a regenerative combustion furnace capable of effectively preventing a leakage of treating gas at a low cost. SOLUTION: A treating gas line L1, an exhaust gas line L2 and a purging line L3 are respectively connected to regenerative burners A, B and C of a combustion furnace 1. A ball valve V is provided at the lines L1, L2, L3. A sealing gas port P is connected to the valve V to press inject the gas thereinto. Thus, since the leakage of the gas can be substantially completely prevented by the one valve V, the number of the valve V used in the entire system is largely reduced to decrease cost. |
