How burner controllers work

Automatic burner controllers take over numerous safety-related tasks in control technology: They are responsible for the secure firing of gas and oil burners in industrial thermal processing and need to be both easy and comfortable to use.

The burner controllers fires the burner and monitors the flame with the help of ionisation electrodes or an UV sensor tube. In case of breakdown, for instance due to flame failure, the control system puts the machine in safe mode by immediately interrupting the gas supply.


Can be expanded into a burner management system

Depending on the complexity of the application, burner management systems (BMS) such as Honeywell Slate are used to monitor and visualise additional safety-related functions.

Flame monitoring with ionisation electrodes and UV flame detectors

Flame monitoring with ionisation electrodes and UV flame detectors

Continuous flame monitoring is one of the central requirements of EN 746 and an integral safety aspect of modern burner systems. Depending on the conditions on site, there are various methods of flame monitoring.

How does a ionisation electrode work?

One of them is done by way of an ionisation electrode, which is used to detect a steady flame and measure its conductivity. As soon as flame failure is detected, the electrode shuts off the gas supply. When installing the electrode, it is important to place it in the first third of the flame and make sure that the burner is grounded.


How does a UV sensor detect a flame?

During flame monitoring with an UV flame detector, the flame’s electromagnetic radiation in the UV spectrum (ideally 210 nm wave length) is measured. This type of sensors is mostly used for the combustion of carbon-containing fuels such as natural gas or oil. The UV flame detector should be placed as close to the flame as possible and be protected against dirt, humidity and heat. 

Gas valves and servo motors

For the gas inlet section and combustion air supply, special valves and actuators are required to regulate pressure and flow rates. Honeywell offers a comprehensive product portfolio in the field of Thermal Solutions, including the following:
