What is a fuel oil furnace ignition transformer?

A fuel oil furnace ignition transformer is a critical component in fuel oil heating systems, responsible for generating the high voltage needed to ignite the fuel oil in the burner. This transformer converts low voltage electricity from the furnace’s power supply into a high voltage that creates a spark, initiating combustion of the fuel oil. Proper functioning of the ignition transformer is essential for the efficiency and reliability of the heating system, as it ensures consistent ignition, reduces unburned fuel emissions, and enhances overall system performance. Regular maintenance and inspection of the ignition transformer are vital to ensure its longevity and effectiveness, especially in environments where fuel oil is extensively used, such as industrial applications.
