What is the purpose of a fuel oil filter in an oil burner system?

The purpose of a fuel oil filter in an oil burner system is to remove impurities from the fuel oil. This is crucial because any dirt, debris, or particulate matter present in the fuel can lead to several operational issues. These might include clogging of fuel lines, reduced efficiency, or even failure of the burner system. By ensuring that the oil is clean before it reaches the burner, the filter helps maintain optimal operation and prolongs the life of the equipment. Effective filtration contributes to smoother combustion, which is essential for safety and efficiency in oil burner operations. The other functions listed do not align with the primary role of the fuel oil filter in this context.
