230V Ceramic Heater Element for Pellet Stoves
Application
One special application area for FUBOON’s high temperature ceramic piezo igniter is in heating systems that use solid fuels such as wood pellets as energy source. The challenge here is to
ignite the biomass in a very short time while retaining very low emission values. This can be perfectly achieved by FUBOON’s hot surface ceramic igniter.
Ceramic hot surface igniter for pellet burners need only approx. 1/10 of the energy of that needed by hot air fans and ignition blowers. Their ignition capacity lies between 120 and 200 Watt. Depending
on the positioning of the ignition element in the boiler, the ignition time of approx. 60 seconds is ex-tremely short. This also means minimal emissions!
Igniting wood chips, firewood, coal bricks or other biomass (such as corn, etc.) is possible.
Mass customization is available.
