<p>Device for controlling a damper regulator (9) at heating boilers (1), whereby the control device controls the damper regulator to operate a butterfly damper (6) mounted in a flue (2) in order to completely or partially throttle flue exhausts from the heating boiler via the flue after switching off a burner (27) in the heating boiler. By utilizing a system (32) with incombustible medium (33), comprising a power aggregate (34) substantially beside and /or beneath the flue (2) for driving the damper regulator (9) via said incombustible medium against the action of a resetting device (16), a suitable operation of damper regulators is obtained. Preferably, the system with incombustible medium comprises a pressurized water system. </p> |
