What is an ignition electrode

An ignition electrode is a component used in certain types of heating systems, such as gas-fired furnaces and boilers, to ignite the fuel and create heat. The ignition electrode typically consists of a small metal rod or wire that is connected to an electrical circuit. When an electrical charge is sent through the electrode, it creates a spark that ignites the gas or oil in the combustion chamber, allowing the heating process to begin. Ignition electrodes are often made of materials that are resistant to high temperatures and corrosive substances, such as ceramics or special alloys, to ensure they can withstand the harsh conditions of the combustion process.
