What is the purpose of a flame sensor in an oil burning system?

The purpose of a flame sensor in an oil-burning system is to detect flame presence. This component is crucial for the safe operation of the burner. The flame sensor monitors whether a flame is established and maintained during combustion. If the flame goes out or is not detected, the sensor sends a signal to the control system to shut down the burner, preventing the potential buildup of unburned oil, which could lead to hazardous conditions or even explosions.

In an oil-burning system, ensuring that the flame is present is vital for efficiency and safety. The sensor thus plays a direct role in protecting the system and its users by ensuring that the combustion process is functioning as intended.
