特徴とするダクト遮断シール装置。 This is a device that seals and blocks the flow of exhaust gas by covering the orthogonal cross section of the duct at an appropriate position in the middle of a large-diameter duct such as a boiler exhaust gas duct, and has a large number of small-diameter fluid injection holes opened on one side of the upstream side of the exhaust gas. A shutoff seal body formed of a bag-shaped heat-resistant woven fabric, a storage box into which the shutoff seal body is delivered in a rollable manner, and a fluid supply system connected to one end of the shutoff seal body fixed to the storage box;
A duct cutoff seal device comprising a guide groove and a guide rod for guiding the expansion and expansion of the cutoff seal body due to fluid feeding from the fluid supply system in a direction orthogonal to the duct.
