The louver can be used for control or isolation capability in SCR flue duct applications. The single, parallel louver is used primarily for low leak isolation. The use of blade edge and jamb seals achieves minimal flue gas leakage past the closed parallel louver. Typical leakage can be less than one percent depending on the damper size and system conditions. The single, opposed louver is used for control. The double louver design utilizes two banks of louver blades. Zero flue gas leakage is achieved by pressurizing the area between the two closed banks of blades with ambient seal air. Zero leakage can also be achieved with a single louver design known as the tandem louver. |

The slide gate (or guillotine) is an isolation device for SCR flue duct applications which can be supplied in low leak and zero leak designs. The low leak design is primarily used when a small amount of flue gas leakage past the closed slide gate can be tolerated. Typical leakage can vary from a few percent to less than one percent of flow depending on the type of seal system provided. The zero leak design is used when zero flue gas leakage is achieved by pressurizing the seal chamber located around the periphery of the closed blade with ambient seal air. |

The diverter is an isolation device that can be used for SCR 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. |
