What is the primary purpose of an oil burner’s filter?

The primary purpose of an oil burner’s filter is to remove impurities from the fuel oil. This is crucial because impurities, such as dirt, rust, and water, can cause blockages in the fuel delivery system, leading to inefficient combustion and potential damage to the burner. By ensuring that only clean fuel reaches the burner, the filter helps maintain optimal performance, enhances efficiency, and prolongs the lifespan of the burner components. Clean fuel is essential for achieving the correct combustion process, which in turn affects the overall efficiency and safety of the heating system.
