Abstract
A method and apparatus for isolating one or more of the filter compartments in a baghouse installation wherein an inlet damper having a pair of spaced closure members is provided in the inlet duct of each of the compartments. When the inlet damper associated with one of the compartments is closed to isolate the compartment, the closure members seal off the inlet duct to form a chamber within the duct which is vented to the atmosphere through an air damper adapted to admit heated ambient air into the chamber to prevent the flue gases from seeping into the compartment.
