Here you will find an overview of how HTH ceramic igniter works in wood pellet stoves, wood pellet boilers and woods chips boilers.
HTH ceramic igniters are printed film PTC resistance encapsulated in ceramic alumina to deliver the best efficieny and resist to corrosion. In biomass heating applications, ceramic igniter are use in combination with primary air ventilator or exhaust fan to heat air passing around or throught the heating element. When air blowed in the burner or in the grate reach 200 to 300°C, biomass combustible immediatly ignite.
Compare to convetional cartridge heaters or heat gun, ceramic igniters only use a fraction of power and ignition speed is reduced by 2~3 minutes. Beside as HTH ceramic igniters are impervious to corrosion, they last for long years.
