Your ceramic igniter offers excellent insulation, resistance to high temperatures, wear resistance, and durability. Alumina and silicon nitride ceramic ignitors ensure long service life in your gas furnace systems, burners, and biomass applications.
2. What Is an Ignitor?
2.1 Definition
-
An ignitor is an electrical conductor device used to light or ignite fuel, charges, or fire.
-
Your ignition electrode generates a spark to initiate combustion in your fuel appliances, such as furnaces and burners.
2.2 How Does a Piezo Igniter Work
-
لك piezo igniter consists of a piezoelectric crystal. When mechanical force is applied to the hammer, the crystal generates a high-voltage electrical charge in response to the deformation. The electric charge is transferred to your electrode, and it creates a spark that ignites your gas.
2.3 How Does a Spark Igniter Work
-
For your spark igniter, a high-voltage discharge is created in a small space between two الأقطاب الكهربائية. When power is applied to your module, it creates a spark. The spark ignites your fuel and air mixture. Your flame rod is used to confirm the establishment of the flame.
2.4 How a Furnace Hot Surface Ignitor Works
-
لك thermostat calls for heat, and the inducer motor starts for safe exhaust. The furnace board sends power to the igniter, which converts the electrical energy to heat, and it glows. The gas valves open, releasing gas to the burners. The gas reaches the heated igniter, causing it to ignite.
3. Your Ceramic Ignition Electrode
3.1 How Does a Ceramic Igniter Work?
-
لك سيراميك igniter uses silicon nitride’s 10^14 - 10^15 Ω·cm resistance to generate heat >1000°C. When this heat mixes with air, it heats up to a point where it can ignite your biomass or burners.

3.2.2 Silicon Nitride Igniter
-
Your silicon nitride igniter offers fracture toughness 5.6 to 7.6 MPa·√m, ensuring superior durability and service longevity in your furnace systems.
-
Its fast ignition ensures efficiency, and it also provides temperature and oxidation resistance >1750°C.
3.2.3 Silicon Carbide Igniter
-
Your silicon carbide igniter is a cost-effective option that resists temperatures up to 1750°C.
Note: Silicon carbide is brittle. Careful handling during installation is crucial to prevent cracking and breaking. ISO-certified supply and ongoing maintenance are also required to minimize failures.
3.3 The Ceramic Firing Process
-
In your ceramic firing process, ceramic materials are shaped, dried, and fired at temperatures >1740°F (1000°C). Your grain boundaries get densified, which boosts strength, thermal conductivity, and insulation. Precision in the process is key to your igniter’s reliability and longevity.
