Igniters require specific performance characteristics for proper operation. Standard ceramic igniter approval tests usually involve ignition of values within a specific range of nominal voltages.
Ceramic hot surface ignitors allow gas stoves to produce intense heat quickly and consistently, improving cooking efficiency while simultaneously increasing user safety and lowering energy usage. Their reliability also allows manufacturers to offer improved user safety and cut energy consumption costs.
Ceramic hot surface igniters tend to last much longer than silicon carbide units due to being more durable and less likely to break, unlike their silicon carbide counterparts which may easily crack under pressure and needing repairs. A broken hot surface igniter could mean no heat and the associated repair bill for no heating services in an emergency situation.
An HSI (Hydraulic Spark Ignitor) is the part that lights gas in your furnace or boiler. Like the filament in a light bulb, this part heats up when electricity passes through it and glows red to activate your gas valve. Over time, however, constant heating and cooling of an HSI may lead to it breaking or not functioning correctly.
Ceramic ignitors have quickly become the standard among top pellet grill manufacturers. If you own an older Traeger grill, introducing ceramic ignitors into its system is a great way to upgrade it with one designed to last for more than 100,000 ignition cycles! These high-smoke-intensity (HSIs).
Ceramics must withstand sudden and drastic temperature shifts for proper functioning. Silicon nitride stands up well under such extremes; it boasts extremely high thermal shock resistance while remaining flexible enough to expand and contract without cracking or degrading, helping ensure reliable ceramic igniters.
Current invention ignitors provide lightning-fast time-to-temperature performance at low line voltages (85 percent of nominal voltage). Furthermore, these new ceramic igniters have excellent durability during extended lifespan tests.
With a multimeter, check the resistance of hot surface ignitors when cold. If it measures greater than 75 ohms, this indicates damage that needs replacing with new one. Testing this way ensures the ignition system is operating as it should; proper installation and ignition procedures also contribute to efficient operations.
Volume resistivity of materials (a measure of their ability to resist electrical current) is directly correlated to their free electron density; materials with more free electrons tend to have reduced resistance while materials that allow electric current to pass easily are known as electrical conductors.
Ceramic igniters feature low volume resistivity, which contributes to consistent heating and ignition performance as well as long life and durability. Furthermore, its extremely fast time-to-temperature design enables use with instantaneous water heaters and cooltops which require instantaneous time-to-temperature settings.
In some instances, ceramic igniters feature booster zones of variable resistance levels to allow current to flow effectively while acting as a thermistor effect that limits maximum operating temperature for any given amperage. Such igniters include multiple sub-zones 34a, 34b and 34c of different resistance levels; their variable resistance provides effective current flow while serving as an amperage limiting mechanism that limits operating temperature of hot zone at specific amperage.
Ceramic igniters feature high temperature resistance as well as superior thermal conductivity, which allows them to rapidly reach their target temperatures within a shorter amount of time, decreasing frequency of ignition system failures and increasing reliability in heating systems.
Ceramic igniters offer rapid heating capabilities not limited to wood pellets; they're often employed in various fuel applications including logs, firewood, coal briquettes and biomass (corn). Ceramic igniters also make an excellent replacement for traditional silicon carbide spark igniters in gas ignition systems.
