Flame monitoring plays a vital role in the burner ignition controller, which is embodied in the following aspects:

Ensure safe operation

Preventing the risk of flameout: During operation, the burner may experience flame extinction due to various reasons, such as insufficient gas supply or improper air-to-gas ratio. The flame detector continuously monitors the flame status. If the flame is detected to be extinguished, it immediately triggers an alarm and cuts off the gas supply, preventing further gas leakage and thus avoiding accidents like explosions and fires.

Avoid abnormal combustion: By monitoring the flame, abnormal combustion can be found in time, such as unstable flame, flicker and so on. These abnormal conditions may indicate that there is a fault in the equipment or improper operation parameters. Timely treatment can avoid equipment damage and safety risks.

Ensure combustion efficiency

Optimizing the combustion process: Flame monitors provide information on flame intensity and stability. The burner ignition controller adjusts the supply of gas and air based on this information, ensuring the burner operates at its optimal state, thereby improving combustion efficiency and reducing energy waste. For example, in burner systems with continuous control, temperature control instruments can adjust the opening of the air butterfly valve and regulate the burner power based on the results from flame monitoring.

Ensure combustion quality: stable flame is the key to ensure combustion quality. Flame monitor can ensure the stability of flame, make fuel fully burned, reduce pollutant emissions, meet environmental protection requirements.

Fault diagnosis and maintenance

Timely fault detection: When the flame monitoring is abnormal, such as the flame detection current is not within the normal range, the flame is extinguished, etc., the burner ignition controller will send out a fault signal, prompting the operator to check and repair the equipment in time.

Record fault information: Some advanced burner ignition controllers can also record historical data of flame monitoring to provide basis for fault diagnosis and equipment maintenance. By analyzing these data, technicians can find out the cause of the fault and take targeted measures to repair it, improving the reliability and service life of the equipment.
