Overview of components
The boiler consists of the combustion chamber and the heat exchanger, and
controls the combustion air with the exhaust fan.
The lambda sensor consistently monitors the flue gases. The integrated sensors
monitor the temperatures of the boiler and the flue gas. The turbulators clean the
heat exchanger through a rod. The boiler cleans itself at regular intervals using
the de-ash system. The ash extraction auger transports the fly ash and the grate
ash into the ash box. The ignition of the pellets takes place through the automatic
Ignition
.
