The device that helps to provide a proper draft in an oil furnace by regulating the chimney draft is the barometric damper. This component is designed to maintain the right level of draft by automatically adjusting the opening based on the pressure conditions within the chimney and the furnace.
When the chimney draft is too strong, the barometric damper will close partially to reduce the flow of combustion gases, preventing excessive draft that could lead to inefficient burning or incomplete combustion. Conversely, if the draft is too weak, the damper can open to allow more exhaust out, ensuring that gases escape properly and the furnace operates efficiently.
Proper draft regulation is crucial not only for maintaining the performance of the heating system but also for ensuring safety by preventing the buildup of harmful gases within the home. This makes the barometric damper an essential component of oil furnace systems.
Other devices mentioned, such as pressure regulators and flue dampers, have different functions in the heating system. A pressure regulator is generally used to ensure that the fuel supply maintains proper pressure for combustion, while a flue damper typically closes when the system is off to prevent heat loss but does not manage draft in the same way as a barometric damper. The draft inducer serves to improve
