How many cubic feet of air are required per gallon of oil consumed in oil burners?

In oil burners, the combustion process requires a specific amount of air to effectively burn the oil. The accepted standard is that approximately 2,000 cubic feet of air are necessary for each gallon of oil consumed. This ensures that the oil burns efficiently, producing the necessary heat while minimizing pollutants and unburned fuel. Adequate air supply is critical for achieving complete combustion, which not only improves efficiency but also reduces the risk of issues such as carbon buildup and soot formation in the burner system. Therefore, having a requirement of 2,000 cubic feet of air per gallon establishes a baseline for proper operation within oil-burning equipment.
