What does maintaining proper air flow in an oil-fired furnace help with?

Maintaining proper airflow in an oil-fired furnace is crucial for enhancing combustion efficiency. Adequate airflow ensures that the fuel and air mixture is optimal for combustion, which leads to a more complete burning of the fuel. When the air-to-fuel ratio is correct, it allows for the maximum utilization of the fuel being burned, resulting in higher efficiency and better heat production.

If airflow is insufficient, it can lead to incomplete combustion, which not only wastes fuel but also produces more carbon monoxide and other harmful emissions. Conversely, if there is excessive airflow, it can cool the flame and negatively impact combustion as well. Thus, proper airflow directly contributes to achieving an efficient and stable burn, optimizing the furnace's performance while minimizing excess fuel consumption and emissions.
