What type of oil is commonly used in low-pressure oil burners?

• A. No. 1 kerosene
• B. No. 2 heating oil
• C. No. 4 fuel oil
• D. Vegetable oil

Answer: (B)

The commonly used oil in low-pressure oil burners is No. 2 heating oil. This type of oil is specifically designed for residential and commercial heating systems, making it the standard choice for low-pressure applications. No. 2 heating oil is a refined petroleum product that provides a good balance between energy content and cost, making it efficient for use in burners. In addition to its efficiency, No. 2 heating oil has a relatively low viscosity compared to heavier oils, which means it can be easily atomized by the burner nozzle—an important factor for optimal combustion and heating performance. This is critical in low-pressure burner systems that rely on the ability to vaporize the oil before combustion. The use of No. 2 heating oil ensures that the burner operates smoothly, producing consistent heat while minimizing the production of soot and other contaminants that can result from incomplete combustion. Other options, while they serve specific purposes, do not have the same application in low-pressure oil burners. For example, No. 1 kerosene is often used in more specialized applications where lower pour point and lighter characteristics are required, but it is not the standard for residential heating. No. 4 fuel oil is a heavier blend used primarily in industrial applications and is not suitable for
