Ionization Electrode 8 x 110 mm: Flame Control and Safety in Burners

Reliably verifying whether combustion is occurring in industrial and commercial burners is vital for system safety and efficiency. The ionization electrode is a critical sensor that performs flame monitoring (flame control) in combustion systems, detecting the presence of flame using the principle of ionization.

What is an Ionization Electrode and What Does It Do?

The ionization electrode is a ceramic-insulated metal rod placed within the flame, which allows electric current to be transmitted through the ionized gases. The presence of the flame causes a very low electric current (ionization current) to be generated between the electrode and the burner body (ground).

Main Functions:

• Flame Detection: Continuously checks for the presence of flame.

• Safety Signal: This continuously sends a signal to the control unit (burner control unit) indicating the presence of a flame. If no flame is detected, the burner control unit immediately cuts off the fuel and air supply, ensuring a safe system shutdown (safety).

• Combustion Verification: Continuously confirms that combustion is ongoing to prevent fuel waste and hazardous situations.

Properties of Ionization Electrode:

• Dimensions (8 x 110 mm):

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

  • 110 mm: This indicates the total length of the electrode. This measurement is critical for correctly positioning the electrode in the burner's combustion chamber and ensuring it contacts the most intense area of the flame.

• Material:

  • Metal Rod: Made from high temperature resistant material (usually Kanthal or stainless steel alloys).

  • Ceramic Insulator: Insulates high voltage electrical current, ensuring that current flows only through the flame.

• Durability: It must be a long-lasting spare part as it is constantly exposed to high temperature and thermal stress.

Ionization Electrode Usage Areas:

• Gas Burners: Flame control in natural gas, LPG and other gas-fired boilers, furnaces and heat generators.

• Combi Boilers and Heating Devices: All combustion systems that control the presence and continuity of the flame.

• Industrial Furnaces: Gas-fired industrial processes.
