What is the primary purpose of recirculating fuel oil in an oil burning system?

• A. To filter out impurities
• B. To bring it up to the proper temperature
• C. To increase fuel efficiency
• D. To reduce emissions

Answer: (B)

The primary purpose of recirculating fuel oil in an oil-burning system is to bring it up to the proper temperature. This process is crucial because fuel oil needs to be heated to a specific temperature to ensure efficient combustion. If the fuel oil is too cold, it can lead to poor atomization and incomplete combustion, resulting in reduced efficiency and higher emissions. Recirculating the fuel not only helps maintain the appropriate temperature, but it also can help to mix the fuel thoroughly, preventing settling of any heavier particulate matter. This ensures that when the fuel is fed into the combustion chamber, it is in an optimal state for burning, leading to better overall system performance and efficiency.
