<p>PROBLEM TO BE SOLVED: To prevent the problem of entering side waste gas leaking to a stack by simple duct structure. SOLUTION: In duct structure of a waste gas desulfurizer in which after entering side waste gas 4 from a waste gas feeding duct 6 is led to a gas-gas heater through an inlet damper, it is led to a desulfurizer to be desulfurized and after going side waste gas 4a from the desulfurizer is led to the gas heater, it is discharged to a stack by a waste gas duct 10a through an outlet damper, the waste gas feeding duct 6 and the discharge duct 10a are connected by a bypass duct 19 provided with two bending parts 16 and one contraction part 18, and in the connecting part of the bypass duct 19 in the waste gas feeding duct 6, a gas straightening part 22 for heightening a flow of the entering side gas 4 in the waste gas feeding duct 6 is installed.</p> |
