What type of draft do forced oil burners rely on?

Forced oil burners utilize a forced draft to ensure efficient combustion. In these systems, a mechanical fan or blower is employed to push air into the combustion chamber, creating a controlled and consistent airflow that supports the burning of the fuel. This forced draft system enhances the mixing of air and fuel, resulting in a more efficient and complete combustion process.

Using a forced draft is particularly advantageous because it can overcome the resistance to airflow present in the heating system, ensuring that the appropriate amount of air reaches the burner at all times regardless of any variations in pressure or temperature. This is crucial for the reliable operation of the burner and for maintaining optimal heating performance.

The other types of drafts mentioned do not apply here: natural draft relies on the buoyancy of hot gases rising and drawing in fresh air, which is less efficient in controlled conditions, while induced draft systems typically involve exhaust fans instead of a primary air supply. Inducted draft is not a recognized term within this context. Therefore, forced draft is the correct mechanism for forced oil burners.
