ABSTRACT:
A damper mechanism of the slide gate type includes two curved seal segments positioned in back-to-back abutting relation to function as the primary flue seal. A seal door when closed extends between the upper ends of the seal segments and applies compression to the spaced appart ends to form, in combination with the seal segments, a closed chamber which functions as a secondary seal. Means are provided for applying a thrust force to the upper end of one of the seal segments to move that seal segment into abutting relation with the other seal segment when the slide gate is withdrawn. In a preferred embodiment, the thrust force is applied by the seal door during its closing. In another preferred embodiment, the closed chamber formed by the seal door and seal segments is enlarged and compressed air is pumped into the chamber to improve its functioning as a secondary seal. The seal door when in closed position, and the slide gate when in lowered position, apply a static downward and inward compressive force to the seal segments which results in self-adjustment of the seal segments in response to distortion generated by thermal, chemical or mechanical forces.
