ABSTRACT OF THE DISCLOSURE A damper assembly for closure of a duct for conveying hot corrosive gases is disclosed. The damper assembly comprises a rectangular frame having vertical side members substantially coextensive with and secured to sides of the duct and extending both above and below the duct a distance at least equal to the height of the duct, frame cross members substantially coextensive with and secured to the upper and lower edges of the duct, a top frame cross member spaced from the upper edge of the duct a distance substantially equal to the height of the duct, a damper plate having a length at least twice the height of the duct and a width substantially equal to the width of the frame, said plate having an opening formed therein at one end thereof substantially equal to the duct opening, said damper plate slidably supported within said frame for vertical reciprocal travel whereby the opening in the damper plate can be moved into and out of alignment with the duct, a pair of upper and lower cross-bars pivotally secured to upper and lower ends of said plate respectively mounted in said frame for reciprocal vertical travel therein, piston-cylinder means connected to each end of the upper and lower cross-bars for raising and lowering the cross-bars and damper plate whereby the opening formed in said damper plate can be aligned with the duct, and means for sealing the damper plate against the frame to prevent egress of gas from said duct when said damper plate is in an opened, closed or transitional position.
