What is the normal oil pressure range for no. 6 oil burners?

10 to 20 psi
20 to 30 psi
30 to 50 psi
50 to 70 psi

The correct answer is: 30 to 50 psi

The normal oil pressure range for No. 6 oil burners is typically between 30 to 50 psi. This range is established to ensure efficient operation and optimal atomization of the fuel for combustion. Proper oil pressure is essential because it affects the burner’s ability to deliver fuel in a fine mist, which is necessary for complete combustion. Oil burners require a specific pressure to maintain the proper fuel-air mixture, prevent carbon buildup, and ensure the safe operation of the boiler system. When operating within this pressure range, the system can effectively burn No. 6 fuel oil, which has a higher viscosity than lighter oils and requires adequate pressure to atomize properly. Operating outside of this specified range could lead to incomplete combustion, reduced efficiency, and potential operational issues. Therefore, understanding the correct oil pressure range is vital for anyone involved in maintaining or operating low-pressure boilers using No. 6 oil.
