Question: 1 / 400

How many cubic feet per minute (cfm) of air must ventilation provide for each gallon of oil?

20 cfm

30 cfm

36 cfm

The correct answer is based on established guidelines for oil combustion in heating systems. For oil-fired boilers, proper combustion is crucial for efficiency and safety. The standard requirement is that for every gallon of oil burned, approximately 36 cubic feet of air per minute (cfm) is necessary. This ensures that there is sufficient oxygen available for complete combustion, which helps to minimize the production of harmful emissions and maintain effective operation of the boiler.

Understanding this concept is essential, as providing adequate ventilation not only affects the performance of the boiler but also impacts indoor air quality and energy consumption. Each option presented reflects different ventilation rates, but 36 cfm aligns with the industry standards needed for efficient oil burning, making it the optimal choice.
