Yuanming offers various types of ignition electrodes and flame sensor electrodes according to the client's requests and drawings. They are mainly used in gas boilers, water heaters, stoves, grills, etc.
Ignition electrodes and ionization probes are produced from high-quality materials.
* The central electrode is generally made of a unique fireproof material, resistant to high temperature and electrochemical corrosion (seen more in gas boilers and gas heaters)- Kanthal material.
* The outer insulator is made of alumina ceramic with high mechanical strength, heat resistance, high voltage resistance (usually 18kV), and high Al2O3 content.
* Some electrodes also have mounting brackets on ceramics, and we usually like to be made of 304 stainless steel, which gives the product a longer life.
They ignite gaseous fuels in gas burners and operate on the principle of high voltage flashover. The ignition electrode must be outside the flame. Only the central electrode is in the flame. The ignition electrode and ionization probes are usually used in combination in the combustion chamber of a gas-burning appliance (the ignition electrode can also be used as an ionization probe). However, the space between them needs to be designed by a professional engineer for you.
