PROBLEM TO BE SOLVED: To replace an exhaust gas duct with dust accumulated with an exhaust gas duct free from dust in a short operation stop time. SOLUTION: The exhaust gas duct Dd constituting an exhaust gas flow channel and an exhaust gas duct De for replacement are travelably constituted, and replaceable by traveling, so that replacement work performed while stopping operation of the facility can be easily performed in a short time, and the operation of the facility can be immediately restarted. As for using the exhaust gas duct Dd demounted from the flow channel this time as the exhaust gas duct for replacement in the next time, the dust removing work can be sufficiently performed during the operation of the facility, and for using a new exhaust gas duct as the exhaust gas duct for replacement of the next time, in place of the exhaust gas duct Dd demounted from the flow channel this time, the replacement work can be performed during the operation of the facility.
