How Does a Ceramic Pellet Igniter Transform Biomass Heating Efficiency?
2025-11-17
Ceramic pellet igniters from GREENWAY® enable <300-second cold-start ignition in wood pellet stoves and industrial biomass boilers. Unlike traditional hot rods, these silicon nitride/aluminum oxide cores withstand 850°C continuous operation while reducing ignition failures by 68% (per ISO 13732-1 thermal testing).

Ceramic Pellet Igniter Critical FAQ
Q: How to tell if the ceramic pellet igniter in my stove is failing?
A: Watch for these symptoms:Extended ignition time (>180 seconds for pellet stoves)Incomplete pellet combustion with black residueError codes: "IGN" faults on Harman/QuadraFire controllersVisible cracks or oxidation pits on silicon nitride core
Q: Why won’t my pellets ignite despite a glowing igniter?
A: Typically airflow/fuel issues - troubleshoot sequentially:
Vacuum leaks: Test door gasket seal with dollar bill
Pellet bridging: Clear hopper/fuel chute obstructions
Draft interference: Install intake air kit if negative pressure >0.05" W.C.
Moisture problems: Check pellet integrity (should snap, not bend)
Q: How does GREENWAY’s corrosion-resistant coating improve igniter lifespan?
A: Two critical mechanisms:
Zirconia-toughened alumina prevents chloride corrosion when burning treated wood
Crystalline silica layer blocks potassium vapor damage from corn fuels (per ASTM C863 testing)
