Ionization Electrode 8 x 85 mm: Flame Control and Safety in Burners

In industrial and commercial burner systems, detecting whether the fuel is burning—that is, monitoring the flame—is a critical step for system safety and automatic control. The ionization electrode is a vital component that controls the burner's flame, detecting the presence or absence of flame and sending a signal to the burner's automatic control.

What is an Ionization Electrode and How Does It Work?

The ionization electrode detects the presence of a flame by using the electrical conductivity of ionized particles within the flame. When the flame ionizes the gas or fuel vapor, a very weak electric current (ionization current) is generated between the electrode and the burner body.

Ionization Electrode Working Principle:

• Flame Detection: The burner automatic (brain) applies a small voltage between the electrode and ground (burner body).

• Signal Generation: When the flame is formed, the electrical circuit is completed thanks to the ionized particles and the micro current (ionization current) created sends a signal to the burner automatic that the flame is present.

• Safety Shutdown: If there is no flame or the current is cut off, the automatic control unit safely terminates burner operation.

Specific dimensions such as 8 x 85 mm ensure that the electrode fits perfectly to the burner model and produces a reliable signal by operating in the correct position.

Properties of Ionization Electrode:

• Dimensions (8 x 85 mm):

  • 8 mm: It refers to the outer diameter of the ceramic insulator.

  • 85 mm: Indicates the total length of the electrode or the length of the ceramic insulator. These dimensions ensure correct positioning of the electrode within the burner and optimal flame detection.

• Material:

  • Metal Rod: It is made of a material (usually alloy steel) that is resistant to high temperatures and is conductive.

  • Ceramic Insulator: Made of ceramic material that is resistant to high temperatures and provides excellent insulation.

• Flame Monitoring: Continuously monitors the presence or absence of flame, ensuring safe operation of the burner for extended periods.

Ionization Electrode Usage Areas:

• Gas Burners: Boilers, furnaces and heating systems operating with fuels such as natural gas and LPG.

• Industrial Furnaces: Industrial furnaces used for process heating.

• Boilers: Steam and hot water boilers.

• Hot Air Generators: Continuous control of the flame in the combustion chamber.
