DIVERTERS
The diverter is an isolation device that can be used for HRSG flue duct
applications. EFFOX manufactures a low leak and zero leak style
diverter. The low leak design is used when a small amount of flue gas
leakage can be tolerated across the closed diverter blade. This amount of
leakage is usually less than one percent of flow. The zero leak design is
used when flue gas leakage past the closed diverter blade is not allowed.
Zero leakage is achieved by sealing the diverter blade against a seal air
chamber pressurized with air. |

STACK ISOLATION DAMPERS
These dampers are used to protect the exhaust system from the elements and
reduce the stack effect when the system is off line. The design can be
equipped with adjustable counter-balances for pressure relief
applications. Electric, pneumatic or manual actuation is available. |
