ABSTRACT:
An absorber tower maintenance isolation system for isolating an absorber tower while maintaining a steam generation plant in operation. An inlet blank-off plate and outlet blank-off plate cooperate with louver dampers in the inlet and outlet ducts to permit shut down or start up of an absorber tower. Closure devices and locking devices act to keep the blank-off plates in position. Equalization devices and duct vent holes allow release to the atmosphere. Further, access is provided to the absorber tower inlet and outlet ducts.
