ABSTRACT:
A device intended for flue gas passages includes a pivotable damper plate which is connected to a regulating device for automatic adjustment of the damper plate between a closed position and an open position in response to the operating condition of an installation connected to a flue gas passage. Adjustment is effected with regard to the economical operating position to prevailing outside wind conditions. An anemometric chamber with an associated diaphragm is arranged to be actuated by the gas pressure in the flue gas passage downstream of the damper plate and is connected to the damper plate in such a way that the degree of opening of the damper plate in the economical operation position is decreased for decreasing gas pressure in the flue gas passage.
