Diverters
The diverter is an isolation device that can be used for HRSG flue duct applications. EFFOX manufactures a low leak and a 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 seating the diverter blade against a seal air chamber pressurized with ambient air.
