    Effective management of flue gas tracts

    Flue gas dampers

    Flue gas dampers are installed in the connection pipe between a boiler and the chimney and close the flue gas path, if the chimney is no longer in use. The flow safeguard prevents the cooling down of the heat generator and the plant room, which helps to save energy. In addition they prevent a possible influx of exhaust gases from other appliances connected with the chimney, for example in the cascade system and have the effect of an exhaust gas silencer if there multiple appliances connected to the chimney.

    Stainless steel or black steel flue gas dampers made by Jeremias are used in combined heat and power plants, emergency power systems, exhaust air technologies and in overpressure operation engines.

    Butterfly valve

    Butterfly valves are used to close the exhaust air pipes in case of negative pressure and overpressure situations. Hand operated as well as motorized flue gas dampers are mostly placed behind the boiler connector to slow down the process of cooling down in case the boiler is switched off. The motor power is adapted to the diameter to bring the damper into the right position in the right moment.

    Throttle valve

    Throttle valves are used to regulate the open cross section of the exhaust path as well as closing it completely. The coordination of bypass routes is easy for the strong motorized completely sealed flue damper motors with at least 90Nm.

    We offer you innovative flue dampers with electronic servo-motors, which can be controlled automatically by the burner, through the BMS systems. In special cases there are implosion dampers (Joukowski-flaps), which ensure a compensation of unwanted pressure fluctuations in the exhaust pipe.
